the number of complete waves that pass a point in a certain amount of time (measured in hertz)
frequency
Which type of waves are used in broadcasting?
Radio waves
a wave that moves at right angles or perpendicular to the direction that it travels
transverse wave
matter through which the energy of a wave travels; can be solid, liquid, gas or a combination of these
medium
Has a smaller wavelength than X-Rays
gamma rays
total distance a wave moves from its resting position
amplitude
part of the electromagnetic spectrum that consists of waves with higher frequencies than radio waves, but lower than infrared waves
microwaves
part of the electromagnetic spectrum that consists of waves with frequencies between those of microwaves and visible light
infrared
A fancy word for light. It does not require a medium to travel
electromagnetic waves
part of the electromagnetic spectrum that consists of waves with high frequencies an high energies
x-rays
