Energy in Travelling and Standing Waves

Energy OF travelling & standing waves

Estimation of frequency of a wave forming a standing wave represented by y = A sin kx cos t can be done if the speed and wavelength are known using speed = "Frequency" xx "wavelength" . Speed of motion depends on the medium properties namely tension in string and mass per unit length of string . A string may vibrate with different frequencies . The corresponding wavelength should be related to the length of the string by a whole number for a string fixed at both ends . Answer the following questions: A string fixed at both ends having a third overtone frequency of 200 Hz while carrying a wave at a speed of 30 ms^(-1) has a length of

Discuss the formation of stationary waves in a closed organ pipe and also explain different modes (nodes, antinodes, overtones) of vibration.

A: When light travels from a rarer to a denser medium, it loses some speed but it doesn't imply a reduction in the energy carried by the light wave. R: Energy carried by a wave depends on the amplitude of the wave and not on the speed of wave propagation.

The displacement of the medium in a sound wave is given by the equation y_(1) = A cos(ax + bt) where A , a and b are positive constants. The wave is reflected by an obstacle situated at x = 0 . The intensity of the reflected wave is 0.64 times that of the incident wave. (a) What are the wavelength and ffrequency of incident wave? (b) Write the equation for the reflected wave. ( c ) In the resultant wave formed after reflection, find the maximum and minimum values of the particle speeds in the medium. (d) Express the resultant wave as a superposition of a standing wave and a travelling wave. what are the positions of the antinodes of the standing wave ? What is the direction of propagation of travelling wave?
