Question

the wavelength of wave having frequency 3*10 of power 13 Hz will be​

Answer 1

frequency=3×10^13 hz

wavelength =speed of air/frequency

wavelength =3×10^8/3×10^13

wavelength =10^8/10^13

10^(-5) m

Answer 2

The wavelength of the wave is $\lambda=10^{-5}\ m$.

Explanation:

Given that,

Frequency of a wave, $f=3\times 10^{13}\ Hz$

We need to find the wavelength of the wave. We know that the speed of a wave is given by :

$c=f\lambda$

$\lambda=\dfrac{c}{f}$

$\lambda=\dfrac{3\times 10^8}{3\times 10^{13}}$

$\lambda=10^{-5}\ m$

So, the wavelength of the wave is $\lambda=10^{-5}\ m$.
