Y8 U6 Reflection and refraction [Revision]

The following diagram shows the ray diagram when a torch light is torched towards a mirror. Which of the following is the correct reflected ray?

• 
• 
• 
• 

When does the light is refracted?

• When light travels in a straight line

• When light is bounced

• When light travels in two different mediums

• When light cannot pass through an opaque object

What is the angle of reflection equal to?

• The angle of refraction

• The angle of incidence

• The angle of absorption

• The angle of light

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.
