Question

· The number of waves in the third orbit of H-atom in
(1) 1
(2) 2
(3) 4
(4) 3​

Answer 1

Answer:

Answer: The correct option is 4.

Explanation: Number of waves in an orbit is written as:

Using de - Broglie equation:

Putting the value of wavelength in above equation we get,

     ....(1)

Now, angular momentum of the third shell is written as:

Putting n = 3 in above equation we get,

Putting the value of (mvr) in equation 1, we get

Number of waves = 3

Answer 2

Answer is the 4 atom
