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

Energy decreases and wavelength gets longer.

Explanation:

The energy of a wave is given by :

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).  

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

if you're asking what comes out, it's steam.
