In medicine, to destroy cancer cells are used.
1 Ultraviolet
2 Visible
3 Gamma
4 Infrared
Explanation:
C In medicine, to destroy cancer cells gamma rays are used. The gamma rays are chosen such that its energy does not harm the healthy cells.

$X$-rays and $\gamma$-rays of the same energies may be distinguished by
1 their velocity
2 their ionising power
3 their intensity
4 method of production
Explanation:
D X-rays and $\gamma$-rays of the same energies but may be distinguished by method of production i.e production of x-rays is an atomic while production of $\gamma$ rays is a nucleus property.

Different wavelengths are coming out of a Coolidge tube in an $\mathrm{X}$-ray experiment. The possible one that is not present of the following is
1 $25 \mathrm{pm}$ (picometer)
2 $50 \mathrm{pm}$
3 $75 \mathrm{pm}$
4 $100 \mathrm{pm}$
Explanation:
A In a Coolidge tube experiment the cutoff wave length for the observed x-ray was found to $25 \mathrm{pm}$. If $50 \mathrm{pm}$ is present then all the wave lengths above it (75 pm and $100 \mathrm{pm}$ ) have to be present. Hence, it is clear that all the wavelengths above the cutoff will be observed where as nothing below it could be produced.

When cathode rays strike a metal target of high melting point with very high velocity, then
1 X-rays are produced
2 $\alpha$ - rays are produced
3 UV waves are produced
4 ultrasonic waves are produced
Explanation:
A When the cathode rays strike a solid target of high atomic weight and high melting point such as tungsten, molybdenum etc. They give rise to highly penetrating radiation called the X-rays.
