Start Quiz
1.

The law of reflection states that

the angle of reflection is always 90°
the angle of incidence equals the angle of reflection
the angle of incidence is larger
light bends on reflection
2.

The normal is

a line at right angles to the surface
the incident ray
the reflected ray
the mirror surface
3.

A ray hits a plane mirror with an angle of incidence of 35°. The angle of reflection is

55°
35°
70°
90°
4.

The image in a plane mirror is

smaller than the object
upside down
in front of the mirror
the same size as the object, upright and laterally inverted
5.

The image in a plane mirror is as far behind the mirror as

twice the object distance
half the object distance
the object is in front
zero
6.

A smooth, shiny surface gives

regular (specular) reflection
diffuse reflection
no reflection
refraction
7.

A rough surface gives

a clear image
no reflection
regular reflection
diffuse reflection, scattering light in all directions
8.

We see non-luminous objects because

light reflects off them into our eyes
they give out light
our eyes send out light
they absorb all light
9.

A ray of light strikes a mirror at 20° to the mirror surface. The angle of incidence is

20°
40°
90°
70°
10.

A periscope uses

one curved mirror
a lens only
a prism only
two plane mirrors at 45°
