Reflection and Refraction

Refraction is when light...

• Bounces

• Transmits

• Bends

• Absorbs

What is happening in this picture?

• Reflection

• Refraction

Refraction is the bending of a wave disturbance as it passes from one _________ into another.

• glass
• medium
• area
• boundary

The velocity of light in vacuum is _______ m/s

• 3x10⁸
• 3x10¹²
• 3x10⁶
• 3x10¹⁰

When light passes at an angle to the normal from one medium into another where its speed is higher

• it is bent toward the normal.

• it always lies along the normal.

• it is unaffected.

• it is bent away from the normal.

Based on the image, as light passes from medium 1 to medium 2

• light speeds up and bends towards the normal

• light speeds up and bends away from the normal

• light slows down and bends towards the normal

• light slows down and bends away from the normal

In what medium does light travel the fastest?

• vacuum
• air
• water
• glass

Which of the following is true?

• When light travels from a vacuum into glass it speeds up.

• When light travels from a vacuum into glass it bends away from the normal.

• When light travels from a vacuum into glass the frequency decreases.

• When light travels from a vacuum into glass the wavelength decreases.

When is light refracted?

• when light cannot pass through an opaque object

• when light is bounced

• when light travels in a straight line

• when light travels in two different mediums

What is the angle of incidence?

• The angle at which light bends in water.

• The angle at which light hits a surface.

• The angle at which light is absorbed by an object.

• The angle at which light bounces off a surface.
