Reflection and Refraction

Reflection is when light...

• Bends

• Bounces

• Absorbs

• transmits

Refraction is when light...

• Bounces

• Transmits

• Bends

• Absorbs

___________ travels in a straight line until something changes its path

• Medium

• Refract

• Reflect

• Light

Which of the following best models how light is reflected?

• An arrow hitting a target

• A ball bouncing off a wall

• An apple falling from a tree

• A marble rolling down a ramp

Light traveling through the air moves in a straight line. An object viewed through water looks different because light rays that travel through water are –

• bent.

• bounced.

• reflected.

• absorbed.

The law of reflection states that

• Angle of incidence = Angle of reflection

• Angle of incidence = Angle of incidence

• Angle of reflection = Angle of translucence

• Angle of reflection = Angle of reflection

The angle of reflection is

• 90 degrees

• 55 degrees

• 45 degrees

• 135 degrees

Refraction happens because light travels _____________ in glass or water compared to air

• Faster

• The same

• At the speed of sound

• Slower

Why does the straw appear to be bent?

• light is reflected

• light is absorbed

• light is turned

• light is refracted

The velocity of light in vacuum is _______ m/s

• 3x10⁸
• 3x10¹²
• 3x10⁶
• 3x10¹⁰
