Why does refraction occur?
irina1246 [14]

Answer:

The answer is C.

Explanation:

Let's take a glass of water as an example. Now, shine a flashlight on it. See it bend the light into a rainbow? That is a example of refraction. When the light enters the water, the water actually slows down and changes its direction, causing the light to come out the other side in a different way. Since water is very dense, it can bend the water and make it different.

elena-s [515]

Tango landed in a site of lower temperature while Foxtrot landed in a site of higher temperature.

<h3>Effect of temperature on speed of sound</h3>

Speed of sound increases with increase in temperature because air molecules acquires more kinetic energy which increases their rate of vibration.

From the information, the speed of sound picked by Foxtrot (258 m/s) is greater than the speed of sound picked by Tango (240 m/s).

We can conclude that, Tango landed in a site of lower temperature while Foxtrot landed in a site of higher temperature.
