According to Moseley's law, the frequency (v) of the \(K_\alpha\) line and the atomic number \(Z\) of the element have the relation ( \(A\) and \(B\) are constants)
B We know that, According to the Moseley's law frequency (v) of the \(\mathrm{K}_a\) line with atomic number \(Z\) and constant \(A\) and \(B\) \(\sqrt{v}=\mathrm{B}(\mathrm{Z}-\mathrm{A})\) Then, \(\quad \mathrm{B}=\frac{\sqrt{v}}{(\mathrm{Z}-\mathrm{A})}\)

When X-rays are produced
1 heat is generated at the target
2 heat is absorbed at the target
3 the temperature of the target remains constant
4 brilliant light is seen at the target
Explanation:
A When the high-speed electron beam is a strike on the metal base, it generate excessive heat and \(\mathrm{X}\)-rays are produced.

Dual nature of radiation and Matter
142620
A direct X-ray photograph of the intenstines is not generally taken by radiologists because
1 intestines would burst an exposure to X-rays
2 the X-rays would be not pass through the intestines
3 the X-rays will pass through the intestines without causing a good shadow for any useful diagnosis
4 a very small exposure of X-rays causes cancer in the intestines
Explanation:
C A direct X-ray photograph of the intenstines is not generally taken by radiologist because the \(\mathrm{X}\)-rays will pass through the intestines without causing a good shadow for any useful diagnosis.
