MHT CET 2025 Physics question
When the electron orbiting in hydrogen atom goes from one orbit to another orbit (principal quantum number = n), the de-Broglie wavelength () associated with it is related to n as
Answer: (D)
Solution
Bohr's quantisation condition with de-Broglie wavelength gives , i.e. . Since the radius of the th Bohr orbit is \propto$
