1.
If the kinetic energy of a free electron doubles, it�s de-Broglie wavelength changes by the factor- $2$
- $\frac{1}{2}$
- $\sqrt{2}$
- $\frac{1}{\sqrt{2}}$
2.
An element with atomic number $Z = 11$ emits $K_{\alpha} -$ X-ray of wavelength $\lambda$. The atomic number which emits $K_{\alpha} - $ $X$-ray of wavelength 4$\lambda$ is- 4
- 6
- 11
- 44
3.
The kinetic energy of an electron get tripled then the de-Broglie wavelength associated with it changes by a factor- $\frac{1}{3}$
- $\sqrt{3}$
- $\frac{1}{\sqrt{3}}$
- 3
4.
A direct $X$ -ray photograph of the intenstines is not generally taken by radiologists because- intenstines would burst an exposure to X-rays
- the X-rays would be not pass through the intenstines
- the X-rays will pass through the intenstines without causing a good shadow for any useful diagnosis
- a very small exposure of X-rays causes cancer in the intenstines
