<span> Displacement of the medium perpendicular to the direction of propagation of the wave. that would be your answer</span>
Explanation:
Assuming we can turn on the lightbulb from any distance with a device. We can gradually increase the distance that separates us from lightbulb, in this way, if the speed of light is finite we can see a temporary delay between the moment we turn on the lightbulb and the moment in which we observe its light.
Bc the equator is constantly facing the sun while the earth rotates
A change in momentum is called impulse.
Either 25% or 75%. does it to how much is wasted or the difference in the input and waste?
