A source is moving with constant speed `upsilon_(s) = 20 m//s` towards a stationary observer due east of the source. Wind is blowing at the speed of `20 m//s` at `60^(@)` north of east. The source has frequency `500 H_(Z)`. Speed of sound `= 300 m//s`. The frequency resgistered by the observer is approximately

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

A source emits sound with a frequency of 1000 Hz. It is moving at 20 m/s toward a stationary reflecting wall. If the speed of sound is 340 m/s an observer at rest directly behind the source hears a beat frequency of

An observer moves on the same line on which two sources of sound of frequency 660 Hz are present. The observer observes beat frequency of 10Hz . If speed of sound is 300m//s then speed of the observer is:

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 is travelling with a velocity of 30(m)/(s) towards a stationary observer. If actual frequency of source is 1000 Hz and the wind is blowing with velocity 20(m)/(s) in a direction at 60^@C with the direction of motion of source, then the apparent frequency heard by observer is (speed of sound is 340(m)/(s) )
