The wavelength of the photon is approximately 476 nanometers. This falls within the blue region of the visible light spectrum.
The wavelength of the photon can be calculated using the following equation:
λ = c / ν
where:
λ is the wavelength of the photon (in meters)
c is the speed of light in a vacuum (approximately 3.00 x 10^8 m/s)
ν is the frequency of the photon (in seconds^-1)
Substituting the given values:
λ = (3.00 x 10^8 m/s) / (6.3 x 10^14 s^-1) ≈ 4.76 x 10^-7 m
Converting the wavelength to nanometers:
λ ≈ 4.76 x 10^-7 m * (10^9 nm/m) ≈ 476 nm
Question:-
What is the wavelength of a photon of blue light whose frequency is 6.3 x 10^{14} s^{−1}?
