Question

Number of waves in the third Bohr’s orbit of hydrogen will be

Answer 1

◇◇◇In general, the number of waves made by a Bohr electron in an orbit is equal to its quantum number.◇◇◇ Thus the circumference of the 3rd orbit is equal to 3 times the wavelength of electron i.e. the electron makes threerevolution around the 3rd orbit.◇◇◇
