does a 700 nm photon have more or less energy than a 400 nm photon? more less correct: your answer is correct. by what factor more (or less)? enter your answer as e700 nm e400 nm . e700 nm e400 nm

Respuesta :

It is the 400 nm photon that has the greater energy by a factor of 1.77.

What is the wavelength?

We know that the wavelength has to do with the horizontal distance that is covered by a wave. We know that the longer the distance that is covered then the weaker the wave. In other words, the wavelength of the wave is inversely proportional to the to the energy of the wave. The greater the wavelength, the lesser the energy.

Let us now find the energy of each of the wavelengths;

E = hc/λ

E = energy of the light

h = Plank's constant

c = speed of light

λ = wavelength

For the  700 nm photon;

E = 6.6 * 10^-34 * 3 * 10^8/ 700 * 10^-9

E = 2.8 * 10^-19 J

For the 400 nm photon;

E = 6.6 * 10^-34 * 3 * 10^8/ 400 * 10^-9

E=  4.95 * 10^-19 J
