Sonar signals and infrared light are are used to send messages to submarines deep under water. if we compare the two signals, which statement describes a difference between the two?
a) the sonar signal gets there faster and is clearer.
b) the infrared light gets there faster and is clearer.
c) the sonar signal gets there faster but is more likely to get distorted.
d) the infrared light gets there faster but is more likely to get distorted.

The correct answer is B.

Explanation:

In the given problem, Sonar signals and infrared light are are used to send messages to submarines deep under water.

Infrared light is a electromagnetic wave. It travels with the speed of light.

Sonar wave travels at the speed of the sound in water. Sound is a mechanical wave. The speed of the electromagnetic wave is faster than the mechanical wave. Therefore, the infrared light gets there faster and is clearer.

Therefore, the correct answer is B.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
