A Monochromatic Laser Is Exciting Hydrogen Atoms From The N=2n=2 State To The N=5n=5 State. Part A What Is The Waveleng
A monochromatic laser is exciting hydrogen atoms from the n=2n=2 state to the n=5n=5 state.
Part A
What is the wavelength λ of the laser?
Express your answer to three significant digits in nanometers.
Part B
Eventually, all of the excited hydrogen atoms will emit photons until they fall back to the ground state. How many different wavelengths can be observed in this process?
