Question

When poked by a spear, an operatic soprano lets out a 1200-Hz shriek. What is its wavelength if the speed of sound is 345 m/s

Answer 1

0.3m

Step-by-step explanation:

Given data

Frequency= 1200Hz

Wave length= 345m/s

We know that

v= fλ

substitute

345= 1200*λ

λ = 345/1200

λ= 0.3m

Hence the Wave lenght is 0.3m
