1.
In the reflection experiment angles are measured from
the table edge
the ray box
the mirror surface
the normal
2.
A graph of angle of reflection (y) against angle of incidence (x) should be
a straight line with gradient 1
a straight line with gradient 2
a curve through the origin
a horizontal line
3.
Which change improves the accuracy of drawn rays?
Marking the dots close together
Marking the dots far apart
Drawing the normal by eye
Using a thick pencil
4.
No parallax between a pin and the image means
the pin touches the mirror
the image is real
the mirror is rough
they are in a straight line from the eye
5.
An object is 8 cm in front of a plane mirror. The image is how far behind the mirror?
8 cm
16 cm
It cannot be found
4 cm
6.
Which is a source of random error in the experiment?
Using a protractor that reads 2° too high on every measurement
Reading the protractor scale slightly differently each time
Using a mirror that is too big
Using a ray box instead of a torch
