Question

If the frequency of a wave is doubled, its wavelength

• A. becomes doubled
• B. remains same
• C. becomes half of the original
• D. none of these

Answer 1

The correct option is C becomes half of the original

the relation between frequency and wavelength is

$n=\frac{v}{\lambda }$

(v is velocity, n is frequency and T is time-period)

so if frequency is doubled wavelength will become half of the original as velocity of sound is constant.

so the answer is C.
