Step-by-step explanation:

It is given that,

Frequency of the wave,
$f=5.45* 10^(14)\ Hz$

We need to find the wavelength of an EM wave. The wavelength of the light is given by :

$\lambda=(c)/(f)$

c is the speed of light

$\lambda=(3* 10^8\ m/s)/(5.45* 10^(14)\ Hz)$

$\lambda=5.5045* 10^(-7)\ m$

or

$\lambda=550.46\ nm$

So, the wavelength of light is
$\lambda=550.46\ nm$ . This is the wavelength of green light. Hence, this is the required solution.
