3 cards from this section. Quick, good the night before a test.
What is an electromagnetic wave?
Think of light and radio waves.
Define amplitude.
It’s related to the energy of the wave.
What type of wave does not require a medium to travel?
Think about how light travels in space.
True or False: The higher the frequency of a wave, the shorter its wavelength.
Remember the relationship between frequency and wavelength.
A radio wave has a frequency of 1 MHz. Calculate its wavelength in meters.
Use the electromagnetic wave speed and the frequency convert to standard units.
If a light wave’s speed is 3 x 10^8 m/s and has a wavelength of 500 nm, what is its frequency?
Make sure to convert nm to meters.
