Question

Establish the relationship between speed of sound , its wavelength and frequency. If velocity of sound in air is 340 m/sec , calculate (1) wavelength when frequency is 256 Hz. (2) frequency when wavelength is 0.85 m

Answer 1

HI FRIEND ✋ ✋

HERE IS YOUR ANSWER ⬇ ⬇

RELATIONSHIP BETWEEN SPEED OF SOUND, WAVELENGTH, FREQUENCY :-

Speed = distance / time

V = wavelength / time

V = wavelength × 1/time

Frequency = 1/time

V = wavelength × frequency

1) Wavelength = speed / frequency

= 340 / 256

= 1.32 m

2) Frequency = speed / wavelength

= 340 / 0.85

= 400 HZ

HOPE IT HELPS !!!!!!!

Answer 2

Hii,

v= speed of sound

Lambda = wavelength

F = frequency

Speed = distance / time .

v = lambda / time

We know f = 1/T

v = lambda × 1/T ----- (1)

Put value of f in equation (1)

v = lambda × f

A) v = lambda × f

340 = lambda × 256

Lambda = 340/256

Lambda = 1.32 m

B) v = lambda × f

340 = 0.85 × f

f = 340/0.85

= 400 Hz

Hope this will help you......
