PhysicsEasysingle choice

The frequencies $(f)$ of $K_{α}$ lines of different materials $(z)$ are plotted on a graph as shown in figure. Choose the correct variation which satisfies the Moseley's law.

Options:

Answer:

Solution:

Moseley's law: $f = a (z - b)$ . So $f = a^{2} (z - b)^{2}$ , a parabola meeting the z-axis at $z = b$ . Only curve 4 has this form.
