Nothing happens. The frequency is determined at the source,
and it doesn't change along the way.
The photosynthetic wave interaction between visible light and a photosensitive part of a plant is very important t how plants use light to grow.
The frequency range and intensity levels of this light, I don't know.
Maybe the above ???
Momentum = (mass) x (speed) = (1 kg) x (0.01 m/s) = 0.01 kg-m/s
Answer: As Earth spins on its axis, we, as Earth-bound observers, spin past this background of distant stars. As Earth spins, the stars appear to move across our night sky from east to west, for the same reason that our Sun appears to “rise” in the east and “set” in the west.
Explanation:
The Ozone layer in the atmosphere absorbs the UV rays
