Multiple Choice

What characteristics of the EM spectrum causes the different properties of each of the waves in the EM spectrum?

• All waves in the EM spectrum have the same frequency, wavelength and speed, the unique properties come from the object it interacts with.

• All waves in the EM spectrum have the same wavelength, the frequency and the speed of the wave change, making unique properties of each wave in the EM spectrum.

• All light waves in the EM spectrum travel the same speed, the wavelength decreases and the frequency increases, making unique properties of each wave in the EM spectrum.
