The Speed Of A Wave In A Medium Is 960 M/s. If 3600 Waves Are Passing Through A Point In The Medium In  minute, Then Calculate The Wavelength.

If a spring extend by x on loading, then the energy stored in the spring is (T is the tension in the spring and k its force constant)

A pulse travels along a stretched string and reaches the fixed end of the string. It will be reflected back with

At which temperature will the velocity of sound at 27^oC become double?

The equation of a travelling wave is

Where y is the microns, t in seconds and x in metres. The ratio of the maximum particle velocity and velocity of the wave is

Due to Doppler effect, the shift in the wavelength observed is 0.1 Å, for a star producing a wavelength 6000 Å. The velocity of recession of the star will be  

A particle, with restoring force proportional to displacement and damping force proportional to velocity is subjected to a force F sin ωt. If the amplitude of the particle is maximum at ω = ω₁ and its energy is maximum at ω = ω₂, then (ω₀ is the angular frequency of natural oscillations of the particle)

A vehicle with a horn of frequency n is moving with a velocity of 30 ms^–1in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency (n + n₁). If the sound velocity in air is 300 ms^–1,  

Two springs of constants k₁ and k₂ have equal highest velocities while executing S.H.M. If their masses are equal, the ratio of their amplitudes will be

The velocity of sound is the greatest is

What is the frequency of radio waves transmitted by a station, if the wavelength of three waves is 300 meter?
