Question

the ratio of frequency of the two mechanical waves in a medium is 3:4. find the ratio of their wavelength and time period?​

Answer 1

Answer:

λ = v / f

In a medium both will travel with same velocity

So,

Ratio of wavelength = 1 / Ratio of Frequency

= 1 / (3 : 4)

= 4 : 3

Time period = 1 / Frequency

Ratio of time period = 1 / Ratio of Frequency

= 1 / (3 : 4)

= 4 : 3
