What are these mirrors called? B C A

How would the incident ray reflect off a plane mirror. Draw it How would the incident ray reflect off a plane mirror? Draw it. Label any rays and angles

What is the name of the point where the incident ray hits the reflecting surface?

What are the two types of reflection?

What is the difference between diffuse reflection and specular reflection?

Which of these would be specular reflection Which of these would be specular reflection? Which would be diffuse reflection? Light reflecting off a calm lake Light reflecting off a painted wall Light reflecting off aluminum foil Light reflecting off a shiny metal

What are the two laws of reflection?

What is the difference between a real and virtual image?

What are the two possible attitudes of an image?

What are the shapes of a concave mirror and a convex mirror?

What happens to light rays that hit a concave mirror?

What happens to light rays that hit a convex mirror?

What is the point where light rays converge?

Draw the image of the ray diagram

For the ray diagram, what is the size, attitude and type? Black arrow = object Red arrow = image

For the ray diagram, what is the size, attitude and type? Black arrow = object Red arrow = image

For the ray diagram, what is the size, attitude and type? Black arrow = object Blue arrow = image

What is the line through the centre of a mirror called?

Which type of mirror will magnify an object Which type of mirror will magnify an object? (magnify = make it look larger)

Complete the table Plane Mirror Concave Mirror (closer than focal point) Concave Mirror (farther than focal point) Convex Mirror Size Attitude Location Type of image

What happens as light travels from air to water?

What do concave and convex lenses look like?

Draw and describe what happens to light rays that pass through a concave lens.

Draw and describe what happens to light rays that pass through a concave lens.
