At Normal Temperature And Pressure The Speed Of Sound In Air Is 332 M/s. What Will Be The Speed Of Sound In Hydrogen (i) At Normal Temperature And Pressure, (ii) At 546oC Temperature And 3 Atmospheric Pressure? (Air Is 16 Times Heavier Than Hydrogen).

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

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.

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

At a pressure of 10⁵N/m² the volume strain of water is  Calculate the speed of sound in water. (Density of water = kg/m³).

The speed of sound in oxygen is 635 m/s. Find out the speed of sound in a mixture of hydrogen and oxygen in which the ratio of hydrogen and oxygen volumes is 4:1.
