Question

4.
A speaker emits sound of frequency 'f' Hz and another speaker emits sound of frequency '2f' Hz,
Compare the wavelengths of the two sound waves?​

Answer 1

Answer:

let sound speed be y and wavelength be x

f=yx(speed× wavelength

as

2f=yx'

wavelength and speed onlyshould change as in different medium but here it's in same medium so speed of sound is same

f=yx'/2

x/x'=1/2

Answer 2

Explanation:

let sound speed be y and wavelengths be x

f=yx'

as

f=yx'/2

x/x'=1/2
