If a wave has a frequency of 10 Hertz, what is its period in seconds?
.1 or 1/10 seconds
Microwaves have a shorter ___________ than radio waves
Wavelength
What is a the name of the waves that can travel through the vacuum of space?
electromagnetic waves
What is the entire group of electromagnetic waves called
the electromagnetic spectrum
If you are given a wave's frequency, and its speed, how can you find its wavelength
divide speed by the frequency
The EM wave associated with heat
Infrared
Waves like sound waves travel faster in less dense materials. True or False
False, waves travel faster in a medium with a higher density
In longitudinal waves, instead of troughs and crests you have what?
Compressions and rarefactions
