Types of Waves
What do waves transfer?
Energy
This is the name of the lowest point on a transverse wave.
What is the trough?
If a wave has a frequency of 5 Hz and a wavelength of 2 meters, what is the speed? Show your work
What is 10m/s?
What is reflection?
Bluetooth, GPS, and internet routers all use this type of electromagnetic radiation.
Radio waves
What type of waves requires a medium to travel through?
This is the distance from one crest to the next crest, or from one trough to the next.
What is the wavelength?
A wave travels at 300 m/s and has a frequency of 60 Hz. What is the wavelength?
5 meters
This happens when a wave bends as it passes from one medium to another.
What is refraction?
This type of EM radiation allows us to see the world in color.
Visible light
What type of waves can travel through a vacuum like outer space?
This part of the wave measures how tall the wave is from the resting position to the crest.
What is the amplitude? (tells you how much energy the wave is carrying)
A wave has a speed of 500 m/s and a wavelength of 10 m. What is its frequency?
50 Hz
What is diffraction?
This type of radiation has higher energy than visible light and can cause sunburns.
UV radiation
In this type of mechanical wave, the particles of the medium move perpendicular to the direction the wave travels.
What is a transverse wave?
This is the line that represents the wave's resting position, before any energy moves through it.
What is the resting position (or equilibrium line)?
This effect explains why a siren sounds higher in pitch as it approaches you and lower as it moves away.
What is the Doppler Effect?
This occurs when two waves meet and combine to make a bigger or smaller wave.
What is interference?
What four types of electromagnetic radiation would a cell phone use?
radio waves, microwaves, infrared, and visible light
Sound is an example of this type of mechanical wave, where particles move back and forth in the same direction as the wave.
Longitudinal wave
This is the number of wave cycles that pass a point in a certain amount of time (usually one second).
What is the frequency?
A train whistle has a frequency of 400 Hz. If the train is moving toward you, what happens to the perceived frequency and wavelength?
What is the frequency increases and the wavelength decreases?
This is when the energy of a wave is taken in by the material it hits, rather than being reflected or transmitted.
What is absorption?
X-rays and gamma rays have this in common when compared to other EM waves
What is they have the highest frequencies and shortest wavelengths?
