The EM spectrum is the ENTIRE range of EM waves in the order of increasing
frequency and decreasing wavelength.
As you go from left-right, the wavelength gets smaller and the frequencies
get higher. This is an inverse relationship between wave size and frequency. (As one
goes up, the other goes down.) This is because the speed of ALL EM waves is the
speed of light (3x108m/s)
For this activity, arrange the EM spectrum in the order from the longest
wavelength to the shortest wavelength. Write down the answer on your activity
