MHT CET 2026 Physics question

The de Broglie wavelength of the electron in the ground state is and that in the n = 3 level is then is given by

(A)
(B)
(C)
(D)Correct

Answer: (D)

Solution

In Bohr's model the electron's angular momentum is quantised, , and the de Broglie wavelength is . Combining, , i.e. exactly de Broglie wavelengths fit around the -th orbit.
