What is mean by quantisised angular momentum? Explain.

Solution

Quantized means there is fixed unit with which you can use measure all the values or you know what are the allowed values of change.

Like 1 full Banana is the quanta to calculate the total number of full Banana in a box or 1 full Banana is the allowed value of change while calculating the number of full Bananas.

In quantum mechanics in process of solution of Schrodinger Equation for H atom.

Angular momentum is related by L^2 = [l(l+1)] * h^2 (read as h cross).

Here orbital angular momentum operator(angular momentum in general) L^2 have fixed values depending on set of angular quantum number l.Where l is a non-negative integer 0,1,2,3..

So, you can calculate all the values of L^2 with the help of quantum l.
l also describes the orbital s,p,d,f... for o,1,2,3 respectively.
