Calculate the frequency of a wave with a wavelength of 8.00x10 m. In what region of the electromagneti spectrum is this?

zheka24 [161]

<em>The frequency of the wave with a wavelength of is</em> <u>3.748 × 10 ⁶ /s</u>.

I attached the working and the answer to the question below. I hope I was able to help.

Please note that C = speed of light (2.998 × 10⁸ m/s), ν = frequency and λ= wavelength.
