QUESTION 1 What is the frequency, in Hz, of a photon with a wavelength of 1.36×E4 m? CHESTION
Please help me with the following question, explain check that is correct, thank you sm!
The energy levels the electron can occupy in the Li2+ ion can be calculated using the energy level equation. Calculate the frequency (Hz) of the photon absorbed when the electron goes from a n= 4.00 energy level to a n= 5 energy level. Express answer in scientific notation.
