Waves and Energy Review

Electromagnetic energy travels in waves. When we describe electromagnetic waves, we often talk about the wave’s length and frequency. Which of these statements accurately describes the relationship between the wavelength and frequency of an electromagnetic wave?

• If wavelength increases, frequency increases.

• If frequency decreases, wavelength increases.

• If frequency remains constant, wavelength increases.

• If wavelength remains constant, frequency increases.
