Yes, that seems to be more or less the correct wavelength for blue light.
Hydrogen, like all elements, have a characteristic distance between energy levels. The atom can only accept photons of energy that match that distance and then that light is emitted. 500 nm does not match the wavelength of light that matches the wavelength corresponding to the energy gap in hydrogen.

For visible light, the wavelength will usually be specified in nm (nanometers).
The wavelength is 436 nm.
nm = nanometers It is a measure of the wavelength of the light, with energy inversely proportional to the wavelength: E = h / wavelength
Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .
The wavelength is 610 nm.
