📚 Part 1: Multiple Choice

1. Which statement about light is correct?

It travels fastest in a vacuum.

It always bends away from the normal.

It cannot be reflected.

It is only a wave, not a particle.

2. The law of reflection states:

Angle of incidence = angle of reflection.

Reflected ray is always perpendicular to surface.

Incident ray bends towards the normal.

All light is absorbed by mirrors.

3. What happens when light passes from air into glass?

It speeds up and bends away from the normal.

It slows down and bends towards the normal.

It is totally internally reflected.

Its colour changes to red.

4. In a camera, which part mainly controls the amount of light that enters?

Aperture

Shutter

Sensor

Viewfinder

2. Describe briefly how the eye focuses on near objects (mention structure that changes shape):

3. Which two primary colours of light combine to make yellow?

4. Complete the sentence:

5. Match the term (left) with the best definition (right). Draw lines between columns.

A. Reflection

B. Refraction

C. Iris

D. Aperture

E. Concave mirror

1. Controls the amount of light entering a lens or camera

2. Bending of light as it passes between two media

3. Adjusts pupil size in the eye

4. Angle of incidence equals angle of reflection

5. Mirror shape that can form real, inverted images

🖊️ Part 3: Practical / Diagrams

1. Draw a simple ray diagram showing a light ray entering a glass block from air and label the normal, incident ray, refracted ray and direction of bending.

2. Draw the three principal rays for a converging (convex) lens forming a real image of an object. Label the focal point (F), object and image (size and position).
