Reflection

What is the incident ray?

• The ray travelling away from the mirror or object

• The angle at which the light hits the mirror

• The ray travelling towards the mirror or object

What is the reflected ray?

• The ray travelling towards the mirror or object

• The ray travelling away from the mirror or object

• The angle that the light is reflected by the mirror

What is the normal?

• The hatched lines representing the back of the mirror

• A line at 90° to the surface of the mirror

• A line representing the surface of the mirror

What is the angle of incidence?

• The angle between the reflected ray and the normal

• The angle between the incident ray and the reflected ray

• The angle between the incident ray and the normal

The angle of incidence is always equal to what?

• The angle of the normal

• The angle of reflection

• 90°

Which types of surface cause specular reflection?

• Smooth, shiny surfaces

• Rough surfaces

• Translucent surfaces

Which types of surface cause diffuse reflection?

• Rough surfaces

• Translucent surfaces

• Smooth, shiny surfaces

What happens to parallel light rays during specular reflection?

• They are absorbed by the surface

• They are all reflected in different directions

• They are all reflected in the same direction

Which of these can produce clear images?

• Specular reflection

• Absorption

• Diffuse reflection

Which type of diagram is used to show how images are formed by a mirror?

• A light diagram

• An x-ray diagram

• A ray diagram
