Which of the following statements correctly compares the frequency of infrared waves and ultraviolet waves?

(1 point)
Responses

Infrared waves have higher frequency and energy than ultraviolet waves.
Infrared waves have higher frequency and energy than ultraviolet waves.

Infrared waves have higher frequencies but lower energy than ultraviolet waves.
Infrared waves have higher frequencies but lower energy than ultraviolet waves.

Infrared waves have the same frequency and energy as ultraviolet waves.
Infrared waves have the same frequency and energy as ultraviolet waves.

Infrared waves have lower frequencies and energy than ultraviolet waves.

Answer 1

Infrared waves have lower frequencies and lower energy than ultraviolet waves.

Explanation: Infrared light has a longer wavelength than ultraviolet light, so by c = λf its frequency is lower; photon energy E = hf is therefore lower for infrared.
