1.
Which statement correctly describes ROY G. BIV?
a made-up name used to remember the seven colours in order
the scientist who showed in 1666 that white light could be split into colours
the range of colours that can be seen in white light, merging from one to another
a solid shape, such as the triangular glass block Newton used to split light
2.
A rainbow forms when sunlight is:
Absorbed by clouds
Refracted and dispersed by raindrops
Blocked by the Sun
Reflected by the Moon
3.
Nia shines a thin ray of white light through a glass prism. A band of colours forms on the screen between X and Y. Which colour is seen at Y, and why?
Dr Dabour Hub Academy - figure 1
Violet, because it is refracted the most
Red, because it is refracted the most
Violet, because it is refracted the least
Red, because it has the shortest wavelength
4.
The diagram shows the path of sunlight through one raindrop that helps to make a rainbow. What happens to the light at points 1, 2 and 3?
Dr Dabour Hub Academy - figure 2
1 reflection, 2 refraction, 3 reflection
1 refraction, 2 reflection, 3 refraction
1 refraction, 2 refraction, 3 reflection
1 reflection, 2 reflection, 3 refraction
5.
Mira makes a spectrum with a prism, then places a green filter between the prism and the screen, as shown. What will she see on the screen?
Dr Dabour Hub Academy - figure 3
The full spectrum, with every colour tinted green
The whole screen lit evenly with green light
All seven colours, because filters add no colour
Only a green band, where green was before
6.
Kwesi measured how many degrees a prism turned four colours away from their original direction. He could not measure violet. What does the pattern predict for violet?
Dr Dabour Hub Academy - figure 4
More than 39.2°
Less than 38.0°
Between 38.0° and 38.7°
Exactly the same as red
7.
Kiri is looking at a rain shower in front of her, as shown. For which Sun position, A, B or C, is she most likely to see a rainbow in the shower?
Dr Dabour Hub Academy - figure 5
A, above the rain in front of her
B, low in the sky behind her
C, straight above her head
Any of them, as long as it rains
8.
Isaac Newton set up two prisms as shown. The second prism is upside down, and white light reaches the screen. Which conclusion does this experiment best support?
Dr Dabour Hub Academy - figure 6
Prism 1 adds colours to the light and prism 2 takes them away
Only prism 2 refracts the light; prism 1 just lets it through
White light is a mixture that a prism separates
Colours are made when light reflects inside a glass prism
9.
Use the table and what you know about dispersion by a prism. Which statement is correct?
The longer the wavelength, the more the colour is refracted
Every wavelength is refracted by exactly the same amount
The shorter the wavelength, the more the colour is refracted
Green is refracted most because it is in the middle
10.
A weather club recorded when rain showers did and did not give a rainbow. Which conclusion is best supported by their table?
Rainbows can only be seen early in the morning
The Sun must shine through the rain towards you
Rainbows only form when the Sun is in the west
The Sun and the rain must be on opposite sides of you
11.
Omar tried three ways of making a spectrum with a prism. Which statement best explains why test 3 worked best?
The dark room makes it easy to see and a thin ray stops colours overlapping
The dark room makes the prism refract more and the slit adds more colours
The ray box light is a different colour from torch light, so it splits more
The narrow slit reflects the light so that only violet reaches the screen
12.
Hira moved the screen further from the prism and measured the width of the band of colours. Which explanation fits her results?
The prism refracts the light more when the screen is further away
The colours leave in different directions, so they spread out further
Extra colours are added to the spectrum as the light travels on
The width of the spectrum does not depend on the distance at all
13.
Each option pairs a key word with a meaning. Which pairing is correct?
Prism – triangular glass block that disperses light
Spectrum – a single colour of light on its own
White light – light made of one wavelength only
Wavelength – the speed of light inside glass
14.
Each option pairs part of the prism experiment with its job. Which pairing is correct?
White screen – splits the light into colours
Darkened room – makes the prism refract more
Second prism – adds the missing colours
Narrow slit – gives a thin ray of white light
15.
Which colour of light is bent the most by a prism?
Yellow
Red
Orange
Violet
16.
A black object appears black because it:
Absorbs all colours
Reflects all colours
Emits light
Refracts light
17.
The order of colours in a spectrum starts with:
Red
Green
Yellow
Blue
18.
Match the term to its correct meaning: indigo
the scientist who showed in 1666 that white light could be split into colours
splitting light into its different colours
the colour between blue and violet in the spectrum
a solid shape, such as the triangular glass block Newton used to split light
19.
Match the term to its correct meaning: spectrum
a made-up name used to remember the seven colours in order
the range of colours that can be seen in white light, merging from one to another
the colour between blue and violet in the spectrum
splitting light into its different colours
20.
Violet light has _____ of all the colours in the visible spectrum.
the shortest wavelength
the longest wavelength
the fastest speed in glass
the smallest refraction
21.
In a raindrop, the colours in sunlight separate because each colour is _____ by a different amount.
reflected
absorbed
refracted
magnified
22.
A triangular prism gives a wide spectrum but a rectangular block does not, because in the prism the second refraction _____ the colours.
brings back together
turns into white light
reflects back inside
spreads out further
23.
A white object __________ all colours of light.
reflects
emits
absorbs
refracts
24.

True
False
25.
Dispersion means joining colours into white light. - True or false?
True
False
26.
Newton used a glass block in the shape of a triangle to split the light. - True or false?
True
False
27.
The seven colours in order are red, orange, yellow, green, blue, indigo, violet. - True or false?
True
False
28.
A glass prism refracts violet light more than it refracts red light. True or false?
False – red is refracted the most
True – the statement is correct
False – all colours bend equally
True, but only in a darkened room
29.
You are most likely to see a rainbow if you face the Sun while rain is falling behind you. True or false?
True – the statement is correct
True, as light must shine into your eyes
True, but only at midday
False – the Sun must be behind you
30.
Red light travels faster through glass than violet light, which is why red is bent less by a prism. True or false?
False – violet travels fastest in glass
False – colours have the same speed in glass
True – the statement is correct
True, but only in water, not in glass
31.
If only red light is shone through a prism, a full spectrum of seven colours appears on the screen. True or false?
True – the statement is correct
True, as the prism makes the colours
True, but the colours are fainter
False – only red light comes out
32.
Sunlight is white light, so it contains all the colours of the spectrum. True or false?
True – the statement is correct
False – it contains only yellow
False – it contains no colours
True, but only in the morning
33.
A spectrum from a prism is easiest to see in a brightly lit room. True or false?
True – the statement is correct
False – a darkened room is best
True, as more light makes more colours
True, but only with a wide beam
34.
Rotating the prism slowly while watching the screen helps you find the position where the band of colours appears. True or false?
False – the prism must never be moved
False – rotating it removes the colours
True – the statement is correct
True, but only with a red filter
