Class 10 - Light Quiz

1. What causes lateral displacement in a rectangular glass slab?

Reflection of light
Refraction of light
Diffraction of light
Scattering of light

2. Lateral displacement increases when:

Thickness of the glass slab increases
Density of the glass slab decreases
Incident angle is zero
Light travels in air

3. What happens to the light ray when passing through a thick glass slab?

Light bends away from the normal
Light shifts laterally
Light disappears
Light travels faster

4. Why do multiple images form in a thick glass plate?

Due to multiple internal reflections
Due to refraction
Due to light absorption
Due to diffraction

5. Lateral displacement in a glass slab is maximum when:

The slab is thin
The slab is thick and light strikes obliquely
Light falls perpendicularly
Light travels in vacuum
