What kinds of energy are associated with waves on a stretched string? How could you detect such energy experimentally?

Short Answer

Expert verified

The types of energy that are associated with waves on a stretched string are the kinetic energy of the moving string and the elastic potential energy of the string.

Step by step solution

01

Given Data

Stretched string

02

Concept

The addition of kinetic energy and potential energy of an object is defined as the mechanical energy.

03

Determine how high the other ball will go after the collision

  • When a stretched string is displaced from its equilibrium, it will have two kinds of energy. One is the kinetic energy due to the motion of the string and the other is the elastic potential energy of the string.
  • The detection of the kinetic energy of the string is done using an object or measuring device attached to the end of the string. The amplitude and frequency of the vibrations can be measured to compute the energy associated with the string.
  • Hence, the types of energy that are associated with waves on a stretched string are the kinetic energy of the moving string and the elastic potential energy of the string. Attaching an object or measuring device to the end of the string can be used to detect this energy.

Two organ pipes, open at one end but closed at the other, are each 1.14m long. One is now lengthened by 2.00 cm . Find the beat frequency that they produce when playing together in their fundamentals.

In some applications of ultrasound, such as its use on cranial tissues, large reflections from the surrounding bones can produce standing waves. This is of concern because the large pressure amplitude in an antinode can damage tissues. For a frequency of 1.00 MHz , what is the distance between antinodes in tissue?

Would you expect the pitch (or frequency) of an organ pipe to increase or decrease with increasing temperature? Explain.

A car alarm is emitting sound waves of frequency 520 Hz. You are on a motorcycle, traveling directly away from the parked car. How fast must you be traveling if you detect a frequency of 490 Hz?

On the planet Arrakis a male ornithoid is flying toward his mate at 25 m/swhile singing at a frequency of 1200  Hz. If the stationary female hears a tone of 1240  Hz, what is the speed of sound in the atmosphere of Arrakis?
