Types of Waves
Type of wave that moves the medium perpendicular to the direction of the wave
What is a transverse wave?
Highest point of a transverse wave called
What is the crest?
The distance between one point on a wave and the exact same place on the next wave
What is wavelength?
The equation for calculating wave velocity
What is v = f × λ (velocity = frequency × wavelength)?
The only part of the electromagnetic spectrum humans can see.
Visible light
Type of wave that needs a medium to travel
What is a Mechanical wave (examples: sound, water, seismic)?
Maximum distance particles move from equilibrium in a wave.
Amplitude
Frequency is measured in this unit
What is Hertz (Hz) or number of waves per second?
The speed of all electromagnetic waves
What is the speed of light or 300,000 km/s?
Highest energy waves on the electromagnetic spectrum.
What are gamma rays?
Type of wave can travel through space without a medium
What is an Electromagnetic wave (examples: light, radio waves, X-rays)?
In a longitudinal wave, the places where particles are close together
What is a compression?
As amplitude increases, _____ increases
If a wave has a frequency of 5 Hz and a wavelength of 10 m, what is its velocity?
50 m/s
The direction of the magnetic field to electrical field in an electromagnetic wave.
What is perpendicular?
Type of wave where the medium moves parallel to the wave.
What is a longitudinal wave?
In a longitudinal wave, the places where particles are spread apart
What is a rarefaction?
The relationship between wavelength and frequency.
What is an inverse relationship (one goes up, the other goes down)?
Two factors that affect the velocity of a wave in a medium
What are Density and temperature?
The electromagnetic spectrum in order from lowest to highest frequency
What are Radio, Microwaves, Infrared, Visible Light, Ultraviolet, X-rays, and Gamma Rays?
Why doesn’t sound travel in space?
No medium in space; sound is mechanical
Amplitude affects this property of a sound wave
What is volume?
The energy of non-ionizing radiation compared to ionizing radiation
What is lower?
Waves travel fastest in this medium
What are solids?
Ionizing Radiation
What are Ultraviolet rays, x-rays, and gamma rays?
