Electromagnetic radiation with a wavelength of 525 nm appears as green light to the human eye.The energy of one photon of this light is ________ J.

Question

Quizplus · Accepted Answer

The energy of a photon of electromagnetic radiation can be calculated using the equation:
E = hc/λ
where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength of the radiation.
Substituting the given values, we get:
E = (6.626 x 10^-34 J*s * 3.00 x 10^8 m/s) / (525 x 10^-9 m)
E = 3.79 x 10^-19 J
Therefore, the energy of one photon of green light with a wavelength of 525 nm is 3.79 x 10^-19 J, which corresponds to choice C.
