Yes, since it depends on the normal and resultant
The sound wave <span>causes distortion of a medium. The sound wave is formed</span><span> from the reflections of the
sound waves from surrounding material. So, the sound that we hear in a room </span><span>is a combination of the original sound and its reflections off of the various surfaces in the room.</span>
In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.
Similarly, in the second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.
In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).
In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).
The length of the wire is 36 m.
<u>Explanation:</u>
Given, Diameter of sphere = 6 cm
We know that, radius can be found by taking the half in the diameter value. So,
Similarly,
We know the below formulas,
When equating both the equations, we can find length of wire as below, where 
The 
value gets cancelled as common on both sides, we get
The 
value gets cancelled as common on both sides, we get
