See if your prediction is correct by watching the video below. You will then see standing waves in fire and be introduced to end effects.

Do end effects make the natural frequency of a pipe higher or lower?

What will happen to the frequency of notes produced by a violin (string) as the temperature increases?

A pipe that is open at both ends resonates at a fundamental frequency f_open. When one end is covered and the pipe is again made to resonate, the fundamental frequency is f_closed. Which of the following expressions describes how these two resonant frequencies compare?

This video will introduce you to this lecture and also cover a lot of important material about standing waves in air columns. Watch it before attempting the question.

Check if your prediction was correct by watching the video below. Then answer the question.

You stand on the platform at a train station and listen to the train approaching the station at a constant velocity. While the train approaches, but before it arrives, what do you hear?

This video will introduce you to shock waves. Have you ever wondered how supersonic aircraft create sonic booms? Now you will find out.

An airplane flying with a constant velocity moves from a cold air mass into a warm air mass. Does the Mach number

The video below will derive the expression for the change in pressure due to a passing sound wave:

.

Watch it before answering the question.

If you blow across the top of an empty soft-drink bottle, a pulse of sound travels down through the air in the bottle. At the moment the pulse reaches the bottom of the bottle, what is the correct description of the displacement of the elements of air

from their equilibrium positions and the pressure of air at this point?

This video will derive a few expressions for the speed, change in pressure, power and intensity of a sound wave.

A vibrating guitar string makes very little sound if it is not mounted in the guitar body. Why does the sound have greater intensity if the string is attached to the guitar body?

This video will introduce you to boundary conditions and the different standing waves that can be set up in strings.

This video will introduce latent heat and then we will consider phase transitions.

In which case do you think we will observe the most dramatic result?
