Answer:
The blue light
Explanation:
Spectrums of visible light with longer wavelength are absorbed more quickly such as red than those with shorter wavelength. This contributes to why blue with higher energy and shorter wavelength is able to penetrate deeply compared to others that are easily absorbed. Blue light persist longer so it reaches the depth first while so of others are absorbed.
The point In the motion that the balls will be closest to each other is as at the time as the second ball is thrown or lunched.
<h3>Will the first ball always be travelling faster than the second ball?</h3>
No, The two motions are said to be parallel to one another, so they that they both the same timing. Hence, the time it takes for both balls to be able to fall to the ground is said to be the same.
Yes, the both balls have the same speed because of two balls are said to hit the ground, they are said to be done at the same height as well as the same energy and so they have the same speed.
Note that balls will take about 2 seconds to be able to hit the ground.
The horizontal projection velocity of the second ball can be changed so that the balls arrive at the ground at the same time and so the balls will be closest to one another if the second ball is thrown.
