car horn
instruments
speakers
...
The bouncing back of a wave after it hits a barrier
Reflection
material that cuts down the flow of current, but does not stop it
resistor
A disturbance that carries energy from one place to another.
What two forms of energy are being used by solar panels?
Light Energy and Electrical Energy
