What is a wave
disturbance that transfers energy
true or false mechanical waves need a medium to travel through
true
true or false do electromagnetic waves need a medium to travel
false
What is a wavelength
distance between two waves
What is a frequency
number of waves that pass a point
A wave that can travel through a vacuum, such as light
electromagnetic
A wave where particles move perpendicular to the direction of energy transfer, like a wave on a string
transverse wave
What type of wave has the longest wavelength and lowest frequency on the spectrum?
radio waves
This type of wave is used for medical imaging, has a very short wavelength, and is located next to ultraviolet on the spectrum
xray
what is frequency measured in
hertz
The phenomenon where two or more waves overlap and combine to create a larger or smaller wave is called this
interference
This is the energy an electromagnetic wave carries.
amplitude
This is the portion of the electromagnetic spectrum that humans can see
What is visible light?
What is the symbol for wavelength, often represented by a Greek letter?
lambda
This is the relationship between the intensity of a sound wave and its pressure
What is power is equal to pressure squared?
