Refraction Review for Year 6

What is refraction?

• The scattering of light

• The reflection of light

• The bending of light

• The absorption of light

Why does light bend when it passes between two materials?

• Because it changes speed

• Because it changes color

• Because it changes direction

• Because it changes temperature

What happens to light when it passes from air to glass?

• It speeds up and bends away from the normal

• It slows down and bends away from the normal

• It speeds up and bends towards the normal

• It slows down and bends towards the normal

What is the main function of converging lenses?

• Converges parallel rays of light to a point

• Reflects light

• Diverges parallel rays of light

• Absorbs light

What is the main function of diverging lenses?

• Reflects light

• Absorbs light

• Converges parallel rays of light to a point

• Causes parallel rays of light to spread out

What is used to focus light onto the retina for clear vision?

• Refraction

• Reflection

• Absorption

• Scattering

What is the effect of a greater change in speed on light refraction?

• More bending of light

• Less bending of light

• No effect on bending

• Light stops bending

How do lenses refract light to form an image?

• By scattering light

• By absorbing light

• By reflecting light

• By bending light

What is the reason for the bending of light by refraction?

• Changes in color

• Changes in speed

• Changes in temperature

• Changes in direction

What is the use of refraction in lenses and magnifying glasses?

• To reflect light

• To scatter light

• To absorb light

• To focus light
