Question

wave length of light in yellow reigon is 5890 Angstrom calculate the energy is photon of yellow light
​

Answer 1

Answer:

Explanation:

Electromagnetic radiation with a wavelength of 589o nm appears as yellow light to the human eye. The energy of one photon of this light is 3.37 x 10−19 J. Thus, a laser that emits 1.3 x 10−2 J of energy in one pulse of light at its wavelength produces _____ photons in each pulse.
