Question

the frequency of wave 1368 Hertz calculate the wavelength of electromagnetic radiations​

Answer 1

Answer : The wavelength of electromagnetic radiations​ is, $2.19\times 10^5m$

Explanation :

Formula used :

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = frequency of a wave = 1368 Hz = $1368s^{-1}$

$\lambda$ = wavelength of a wave = ?

c = speed of light = $3\times 10^8m/s$

Now put all the given values in the above formula, we get the wavelength of the wave.

$1368s^{-1}=\frac{3\times 10^8m/s}{\lambda}$

$\lambda=2.19\times 10^5m$

Therefore, the wavelength of electromagnetic radiations​ is, $2.19\times 10^5m$
