Energy OF travelling & standing waves

Energy in Travelling and Standing Waves

Standing waves||Energy in a loop OF standing waves||Examples on standing waves

A : There is no energy transferred by standing waves . R : The total energy of each of incident and reflected wave .

Statement-1 : Standing wave of small amplitude is generated on a string. The kinetic energy of any small section of string will be same as its potential energy. Statement-2 : A standing wave can be written as superposition of two travelling waes. For a wave of small amplitude travelling on string, kinetic energy of any string element is equal to its potential energy at any instant.

Find out the equation of the standing waves for the following standing wave pattern.

Stationary waves is called standing waves because

In a standing wave 4 nodes and 3 antinodes are formed between two fixed end of string of length 6 m. Then the wave length of the standing wave is

Superposition OF Waves||Standing Waves

Which of the following travelling wave will produce standing wave , with nodes at x = 0 , when superimosed on y = A sin ( omega t - kx)

Standing waves are produced by the interference of two traveling sinusoidal waves, each of frequency 100 Hz. The distance from the 2nd node to the 5th node is 60 cm. The wavelength of each of the two original waves is
