Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
The energy of a photon of green light with a wavelength of approximately 520 nanometers is about 2.38 electronvolts.
The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Plugging in the values, the energy of a photon with a 9 x 10^-8 m wavelength is approximately 2.21 x 10^-18 Joules.
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the photon in meters. Plugging in the values, the energy of a photon with a wavelength of 9.10^-8 m is approximately 2.18 x 10^-15 J.
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant (6.63 x 10^-34 J*s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the photon.

Transition B produces light with half the wavelength of Transition A, so the wavelength is 200 nm. This is due to the inverse relationship between energy and wavelength in the electromagnetic spectrum.

-- I have to assume that the '520' figure is also a wavelength in nm.-- The energy of a photon is proportional to its frequency. That also meansthat the energy is inversely proportional to its wavelength. So the photonwith the greater wavelength has less energy.-- 720/520 = 1.385The shorter-wave photon has 38.5% more energy than the longer-wave one.-- 520/720 = 0.722The longer wave photon has 72.2% as much energy as the shorter-wave one has.
