Question

The energy of a photone is 3×10^-12 ergs. Then what is its wavelength in nanometres

Answer 1

Answer:

Now, the energy of photon is 3 x 10−19J. Wavelength (nm)=3×10−19J3×108m/s×6. 626×10−34Js=662nm

Answer 2

Answer:

662nm

Explanation:

Now, the energy of photon is 3 x 10−19J. Wavelength (nm)=3×10−19J3×108m/s×6. 626×10−34Js=662nm
