A sound wave with an amplitude of `3cm` starts towards right from origin and gets reflected at a rigid wall after a second. If the velocity of the wave is `340ms^(-1)` and it has a wavelength of `2m`, the equations of incident and reflected waves respectively are :

Sound waves travel from air to water. The velocity of the sound waves in air is 332 ms^(-1) and wavelength is 2m. If the wavelength of the sound waves in water is 850 cm, find its velocity in water

Two sound waves of wavelengths 5 m and 6 m formed 30 beats in 3 seconds. The velocity of sound is

Two waves of wavelength 2m and 2.02 m respectively, moving with the same velocity superpose to produce 2 beats/second. The velocity of the waves is

When a sound wave is reflected from a wall the phase difference between the reflected and incident pressure wave is:

A strain of sound waves is propagated along an organ pipe and gets reflected from an open end . If the displacement amplitude of the waves (incident and reflected) are 0.002 cm , the frequency is 1000 Hz and wavelength is 40 cm . Then , the displacement amplitude of vibration at a point at distance 10 cm from the open end , inside the pipe is
