Chapter 17, Problem 17.1CYU

Check Your Understanding Imagine you observe two firework shells explode. You hear the explosion of one as soon as you see it. However, you see the other shell for several milliseconds before you hear the explosion. Explain why this is so.

Expert Solution & Answer

To determine

The reason for difference in the view of explosion and sound of explosion for the two firework shells.

Answer to Problem 17.1CYU

The difference in the speed of sound and light brings the delay in hearing and seeing the explosion.

Explanation of Solution

Introduction:

The speed of the sound is approximately equal to 340 m/sec while the speed of light is of the order of 10⁸ m/sec.

Hence, the speed of the sound is less than the speed of the light.

The second firework which is seen before than it is heard can be explained on the basis of the different speeds of the sound and light. Sound travels slower than the light, hence the firework was seen before.
While in other case, firework is seen and heard at the same time. This could be the case when firework is close enough that there is a marginal difference in noticing the time difference between receiving the sound and seeing the explosion.Hence, the explosion is seen as soon as it is heard.

Conclusion:

Therefore, the difference in the speed of sound and light brings the delay in hearing and seeing the explosion.
