The wavelength of visible light varies from 380 nm to 750 nm as the color of the light changes from violet to red. Calculate the energy of a photon whose wavelength is 6.8e-07 m.

Respuesta :

Answer:

energy of photon=1.824ev

Explanation:

given wavelength of ligt=6.8×10⁻⁷m=6800A⁰

energy of photon(E)=hc/λ;

and for simplicity

E=12400/λ

where λ is aken in angstorm

and energy in ev

E=12400/6800ev

E=1.824ev=energy of photon
