Parts of a Wave
What do you call the highest point of a wave?
The crest
A Radio wave travels at a speed of 300 m/s with a frequency of 50 Hz. What is its wavelength?
6 meters
Which waves are used for communication?
Radio Waves
What happens to the frequency of a wave as the wavelength increases?
It decreases
True or false: sound waves need a medium.
True
What do you call the lowest point of a wave?
The trough
A high-frequency research wave is traveling through a medium at a speed of 15.6 m/s. If the frequency is recorded as 1.2 Hz, what is the wavelength of the wave?
13 m
Which waves are produced by the sun and give us vitamin D?
Ultraviolet Waves
What happens to the energy of an object as the frequency increases
It increases
True or false: EM waves need a medium.
False
What do you call the length of the wave from one crest to the next.
The wavelength
A Microwave has a frequency of 20 Hz and a wavelength of 5 meters. What is the speed of this wave?
100 m/s
Which waves can kill cancer cells?
Gamma Waves
Which EM wave has the most energy?
Gamma waves
What type of wave is a sound wave?
Compression/longitudinal
What do you call the distance from the middle of the wave to the top?
The amplitude
An Infrared wave travels at a speed of 400 m/s. If its wavelength is measured at 4 meters, what is its frequency?
100 Hz
Which waves are produced by TV remotes?
Infrared Waves
List the colors of the visible spectrum from most energy to least energy
Violet, blue, green, yellow, orange, red
Which EM wave travels faster in a vacuum: gamma waves or radio waves?
They travel at the same speed.
