Question

1. the electromagnetic waves described in the reading are different in which two ways: a. frequency and amplitude b. wavelength and frequency c. wavelength and crests d. frequency and velocity

Explanation:

Electromagnetic waves in the spectrum vary in wavelength and frequency. Wavelength is the distance between successive crests, and frequency is the number of wave - cycles per unit time. These two characteristics distinguish different types of electromagnetic waves.

Answer:

C. wavelength and frequency
