Why does light refract?
speeds up
gets hot
slows down

A student placed a pencil in a cup of water. The pencil appears broken because light-
light travelling from water to air bends away from the normal making the pencil under water look closer to the surface
light travelling from water to air bends towards the normal making the pencil under water look further away
light travelling from air to water bends towards the normal making the pencil under water look higher up
light travelling from air to water bends away from the normal making the pencil under water look closer to the surface
Refraction occurs due to _____________
the change in the wave's speed when it enters a new medium
the wave bouncing off a boundary
the change in the wave's frequency when it enters a new medium
the wave bending around a barrier
The law of reflection states that
the angle of reflection is equal to the angle of incidence
the angle of reflection is greater than the angle of incidence
the image is laterally inverted
the image must be upright and the same size as the object
________ is a reflected sound.
Vibration
Echo
Pitch
Volume

Light travels faster than sound
Sound travels faster than light.
What happens to our hearing if we listen to loud noises all the time?
