Question

The relation between frequency (n) and wavelength ($\lambda$) is given by (v is velocity, n is frequency and T is time-period)

• A. $v=n\lambda$
• B. $n=\frac{\lambda }{v}$
• C. $v=\frac{n}{{\lambda }^2}$
• D. $n=\frac{T}{\lambda }$

Answer 1

The correct option is A $v=n\lambda$

the relation between frequency and wavelength is

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

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

so the answer is A.
