Question

10 What is the wavelength of light emitted when the electron in hydrogen
atom undergoes transition from an energy level with n= 4 to an energy
level with n=2? (Rydburg constant = 1.09677 x 10*7 m-¹)​

Answer 1

Since, electron jumps from n=4 to n=2,(higher energy level to lower energy level) energy will be released in the form of light (photons) whose wavelength we need to find out. Since, range of wavelength of blue light (450–495) nm.
