What happens to an electromagnetic wave as the

frequency (how often a wave hits a crest) decreases?

energy decreases and the wavelength gets shorter

energy increases and the wavelength gets shorter

|

energy decreases and wavelength gets longer

energy increases and the wavelength gets longer

Respuesta :

Answer:

Energy decreases and wavelength gets longer.

Explanation:

The energy of a wave is given by :

[tex]E=hf[/tex]

Where

h is Planck's constant

f is the frequency of the wave

As frequency decreases, the energy of the wave also decreases and wavelength gets longer. Hence, the option is (d).
