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.
1.A=the set of whole numbers less tan 4 ? 2.B=the set of prime numbers less than 19 ? 3.C=the set of first three days of week?
How do you magnetize metal? You can rub a magnet with the metal in single direction for a bunch of times (the more the better), and that will magnetize it to some degree, but i
