Waves

Why can sound travel faster in solids and liquids than in gas?

• Particles cannot move freely

• Distance between particles is closer together

• kinetic energy of particles is low

• particles do not touch each other

• the air around it

• the surface the jump rope is on

• the jump rope

• Bob

When light hits a black object

• It absorbs

• It refracts

• It trasmits

• It reflects

A pencil in water appears broken because

• As light moves from air to water it slows and bends

• The light hits the water and bounces off its surface causing the pencil to look broken

• It is an optical illusion

• The pencil looks bigger, not broken

As something solidifies (turns into a solid) the speed of sound

• increases

• decreases

• does not change

• freezes

Light can be

• reflected, refracted and absorbed by matter

• only absorbed

• only refracted

• reflected and absorbed, but not refracted.
