<u>Answer:</u> The wavelength of the photon is 486.2 nm and it lies in the visible region
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Higher energy level = 4
= Lower energy level = 2
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So,
As, the range of wavelength of visible light is 400 nm - 700 nm. So, the wavelength of the given photon lies in the visible region
Hence, the wavelength of the photon is 486.2 nm and it lies in the visible region
