Waves
The highest point on a wave.
What is a peak or crest?
Energy in the form of vibrations passing through matter.
What is sound?
Occurs when light rays bounce off a surface.
What is reflection?
The transfer of heat that occurs when one thing touches another.
What is conduction?
An electric charge in motion.
The distance between each peak or each trough.

Mr. Smith is walking past the pool. He drops his keys in the pool. He reaches into the pool with a hook but misses the keys every time. Jerome says this is because the light is refracting (bending). Jackie says it is because the light is bouncing or reflecting. Explain who is correct and why.
Jerome is correct because the light is bending as it goes from the air to the water.
A material that keeps heat energy from easily transferring.
What is an insulator?
What is the electric current stopped, so no more electrical energy was changed into light?
