Question

a tuning fork of frequency 256Hz produces wave length 100 cm in air.the speed is​

Answer 1

Frequency = 200 Hz, speed of sound = 330 m/s, number of vibrations = 20.

Therefore, time period = 1/200 = 0.005 s.

Total time = 0.005 * 20 = 0.1 s

Now, distance travelled = speed * time = 330 * 0.1 = 33 m.

brain list please

Answer 2

We know,

V = frequency × wavelength

V = 256 × 1 ( 100cm = 1m)

V = 256 m/s
