Sound waves of wavelength1cm have a velocity of 340 m/s in air. What is their frequency? Can this sound be heard by the human ear?

A sound wave of wavelength 4 cm travels with a speed of 360 m//s .Find its frequency.

In what range of pressure can a sound be heard by human.

What is velocity of sound wave ?

An engine blowing a whistle of frequency 133 Hz moves with a velocity of 60 ms^(-1) owards a hill from which an echo is heard. The frequency of the echo heard by the driver (Velocity of sound in air=340 ms^(-1) )

An open organ pipe of length is 50 cm, If the velocity of sound in air is 320 m/s , then the frequency of its fundamental note will be

A sound wave of frequency 8000Hz travels with a speed of 340 m//s in air. Find its wavelength.

A car with a hom of frequency 620 Hz travels towards a large wall with a speed of 20 m//s . velocity of sound is 330 m//s . The frequency of echo of sound of hom as heard by the driver is

The observer is moving with velocity 'v_0' towards the stationary source of sound and then after crossing moves away from the source with velocity ' v_0 '. Assume that the medium through which the sound waves travel is at rest, If 'v' is the velocity of sound and 'n' is the frequency emitted by the spurce then the difference between apparent frequencies heard by the observer is

An engine blowing a whistle of frequency 133 Hz moves with a velocity of 60(m)/(s) towards a wall from which an echo is heard. Calculate the frequency of the echo heard by the driver. (velocity of sound in air in 340(m)/(s) .)

A motor car blowing a horn of frequency 124 vib//s moves with a velocity 72 km//hr towards a tall wall. The frequency of the reflected sound heard by the driver will be (velocity ofsound in air is 330 m//s )
