<u>Answer:</u> The radiation has a frequency of and is a type of radio wave.
<u>Explanation:</u>
The equation given by Planck's follows:
where,
E = energy of the light =
h = Planck's constant =
= frequency of light = ?
Putting values in above equation, we get:
The relation between frequency and wavelength is given as:
where,
c = the speed of light =
= frequency of radiation =
= wavelength of the radiation = ?
Putting values in above equation, we get:
The radiation having wavelength 0.677 m belongs to radio waves.
Hence, the radiation has a frequency of and is a type of radio wave.
