Question

As the wavelength decreases, the frequency

increases and energy decreases.

decreases and energy increases.

increases and energy increases.

decreases and energy decreases.

Answer 1

I think it would be C. Hope this helps! :)

Answer 2

As the wavelength decreases, the frequency increases and energy increases.
Wavelength and frequency are inversely related, and frequency and energy are directly related. This means that if the wavelength increases, both frequency and energy are going to decrease (since they direction is the same), and vice versa.
