What is an electromagnetic wave?
When the waves arrive out of step, they cancel each other out.
What is destructive interference?
High points of a transverse wave
What are crests?
Meteorologists use Doppler radar to send out this kind of wave to predict the weather.
What are microwaves?
The amount of energy the wave carries
What is amplitude?
How eyes use visible light to see objects.
What are cone or rod shaped cells in the eyes?
