What is constructive interference?
when 2 wave crests or roughs overlap. Results in a larger amplitude and has more energy.
How would you measure a wavelength?
measure the distance between the same point on 2 waves
What is an example of a mechanical wave?
light waves, sound waves, and ocean waves
When a wavelength decreases, what happens to the frequency?
The frequency will increase.
What do waves transfer or give off?
Energy
How is energy transferred from a wave?
The vibrations of particles in the medium
If the frequency of a wave decreases, what will the energy do?
The energy will decrease.
How does the moon shine at night when there is no light?
The sunlight reflects off of the moon.
