Question

Calculate the energy of 100 photons with wavelength of 1000 nm??

Answer 1

Answer:

12.4 eV

Explanation:

Answer 2

Answer:

12.eV

E=hf=hca Ehf= hca. Ehf=hca=1240 eV - nm100 nm=12.4 eV E = hf =hcA= 1240 eV - nm 100 nm = 12.4 eV.

The amount of energy in those photons is calculated by this equation, E = hf, where E is the energy of the photon in Joules; h is Planck's constant, which is always 6.63 * 10^-34 Joule seconds; and f is the frequency of the light in hertz.
