A vehicle, with a horn of frequency n is moving with a velocity of 30 m/s in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency `n + n_(1)`. Then (if the sound velocity in air is 300 m/s)

A vehicle , with a horn of frequency n is moving with a velocity of 30 m//s in a direction prependicular to the straight line joining the observer and the vehicle . The observer perceives the sound to have a grequency (n + n_(1)) . If the sound velocity in air is 330 m//s , then

A vehicle , with a horn of frequency n is moving with a velocity of 30 m//s in a direction prependicular to the straight line joining the observer and the vehicle . The observer perceives the sound to have a grequency (n + n_(1)) . If the sound velocity in air is 330 m//s , then

A vehicle with a horn of frequency f is moving with a velocity of 30 m s^(-1) in a directin perpendicular to the straight line joiing the oserver and the vehicle .The observeer perceives the sound to have a frequency (f+f_1) .If the velocity of sound in air is 300 m s^(-1) :

If a source of frequency n moving with velocity v crosses a stationary observer, then the change in the frequency of sound heard by the observer will be (velocity of sound = V)

A source of frequency n is moving with a uniform velocity v towards a stationary observer. If the velocity of sound is V, then the change in frequency would be -

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s.The speed of the sound id 330 m/s.The frequency heard by the observer is

Velocity of sound is v. Source and observer move towards each other with velocities V_(s) and V_(0) respectively. Wind is blowing with a velocity v_(m) in the direction opposite to the propagation of sound, n is the frequency of the sound. The apparent frequency of the sound heard by the observer is :-
