The vibrating tuning fork is moving slowly and uniformly in a horizontal circular path of radius $8 m$ . The shortest distance of an observer in the same plane from the tuning fork is $9 m$ . The distance between the tuning fork and observer at the instant when the apparent frequency becomes maximum is?

Q. Two turning forks with natural frequencies

340 H z

each move relative to a stationary observer. One fork moves away from the observer, while the other moves towards the observer at the same speed. The observer hears beats of frequency

3 H z

. Find the speed of the turning forks.

Q. Two identical tuning forks vibrating at the same frequency

256 H z

are kept fixed at some distance apart. A listener runs between the forks at a speed of

3.0 m / s

so that the approaches one tuning fork and recedes from the other figure. Then the beat frequency observed by the listener. Speed of sound in air

= 332 m / s

Two identical tuning forks vibrating at the same frequency 256 Hz are kept fixed at some distance apart. A listener runs between the forks at a speed of 3.0 m/s so that he approaches one tuning fork and recedes from the other (figure 16-E10). Find the beat frequency observed by the listener. Speed of sound in air = 332 m/s.

Q. Two identical tuning forks vibrating at the same frequency 256 Hz are kept fixed at some distance apart. A listener runs between the forks at a speed of 3.0m s⁻¹ so that he approaches one tuning fork and recedes from the other figure. Find the beat frequency observed by the listener. Speed of sound in air = 332 m s⁻¹.
