Twice the energy means twice the frequency, and therefore half the wavelength.
The frequency is 666 MHz.
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm

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 .

Frequency = (speed) / (wavelength), so it depends on the speed of the wave. If it's a light wave, then the frequency is (3 x 108) / (15 x 10-9) = 20,000,000 GHz. If it's a sound wave, then the frequency is (343) / (15 x 10-9) = 22.9 GHz.
Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter
A photon with energy 3.0 x 10-19 J A photon with wavelength 525 nm A photon with frequency 7.6 x 1014 Hz A photon with frequency 2 x 1015 Hz
Physically, light of different colors differs:* In their wavelength * In their frequency (note: the longer the wavelength, the lower is the frequency - so, they are inversely proportional) * In the energy per particle (photon) - proportional to the frequency
