question 9 of 33
the diagram shows the electromagnetic spectrum. which statement accurately describes the trends across the electromagnetic spectrum?
visible light
radio waves microwaves infrared ultra
violet x - rays gamma
a. the frequency decreases from left to right across the diagram.
b. the wavelength decreases from left to right across the diagram.
c. the speed of the wave decreases from left to right across the diagram.
d. the energy decreases from left to right across the diagram.

Explanation:

In the electromagnetic spectrum, all waves travel at the speed of light in a vacuum. The energy of an electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength. From left - to - right (radio waves to gamma rays), frequency increases, wavelength decreases, and energy increases.

Answer:

B. The wavelength decreases from left to right across the diagram.
