Answer 1

$\textbf{Hey there}$

$\textbf{Answer}$:

$<b>$

$\underline{\textbf{Gamma Rays}}$:

Gamma Rays were discovered by Rutherford.
They are emitted from the nuclei of some radioactive elements and are electromagnetic waves of very short wavelength. It is denoted by ( $\gamma$ ).

$\underline{\textbf{Properties}}$:

1. Gamma rays are electromagnetic waves and have velocity equal to that of light.

2. Gamma rays are high penetrating. They can penetrate through several centimetres thick iron and lead blocks.

3. They have got small ionising power.

4. They can produce fluorescence in a substance like willemite.

5. They can affect the photographic plate.

6. Gamma rays are not deflected by electric field and magnetic field.

7. Gamma rays out electrons from the surface on which they fall.

8. Gamma rays produce heating effect in the surface exposed to them.


$\textbf{\underline{Applications}}$:


1. Gamma rays are used in radiotherapy. In hospitals, for treatment of cancer.

2. Gamma rays used to produce nuclear reactions.
