Q. State Moseley's law.
The frequency of the spectral line in the qualities X-ray spectrum is directly proportional to the square of the atomic number (Z) of the element considered.
That is ν α Z2 or ν = a(Z - b)
Whereas a and b are constants depending upon the particular spectral line.
Like the centre of mass, the moment of inertia is a function of a body that is concurrent to its mass distribution. Moment of inertia gives a measurement of the resistance of a bod
