Question

A sound source is moving at a speed of 150kmph. The frequency of the source is 50 kHz. If the observer is also moving with a speed of 200 kmph towards the source, what would be the frequency observed by the observer? (Speed of sound= 340ms^-1)

Answer 1

When a sound source is moving at a speed of 150 kmph and has a frequency of 50 kHz, and the observer is also moving towards the source at a speed of 200 kmph, the frequency observed by the observer can be calculated. Given that the speed of sound is 340 m/s, the observed frequency can be determined using the formula for Doppler effect.
