The energy of light whose wavelength is 4,06 x e-11m is 4,8927.e-15 joule.
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
Since the energy of a photon is inversely proportional to its wavelength, for a photon with double the energy of a 580 nm photon, its wavelength would be half that of the 580 nm photon. Therefore, the wavelength of the photon with twice the energy would be 290 nm.
Speed (of a wave) = frequency x wavelengthTherefore, you have to: * Convert the wavelength to meters. * Divide the speed of light - which is 300 million meters/second - by this wavelength. The answer will be in Hz.
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
Any electromagnetic energy whose wavelength is between roughly 390 and 750 nanometers is visible, if some of it happens to enter your eye. By traditional usage as well as international agreement, this type of electromagnetic energy is widely referred to as "visible light".
It is electromagnetic radiation whose wavelength is longer than that of visible light.

First get the wavelength in meters by multiplying Plancks constant (in units of J-sec) times the speed of light (in m/sec) and divided by the energy. Then change to nanometers by multiplying by 1 billion.

shortest wavelengths
The frequency of radiation can be calculated using the formula: frequency = speed of light / wavelength. Given the speed of light is about 3.00 x 10^8 m/s, you can convert the wavelength from nm to meters (1.73 nm = 1.73 x 10^-9 m) and plug in the values to find the frequency.
Energy that is not released as light is released as heat and other EM band radiation.
The energy of a photon is given by E = hc/λ, where h is the Planck constant, c is the speed of light, and λ is the wavelength. Plugging in the values gives E = (6.63 x 10^-34 J s * 3 x 10^8 m/s) / (600 x 10^-9 m) = 3.31 x 10^-19 J.
