What is Compton effect ?
In Coolidge X-ray tube (Modern X-ray tube) how will you vary :
(1) intensity of emitted X-rays?
(2) penetrating power of emitted X-rays?

Explanation

### Step-by-Step Solution

**1. Definition of Compton Effect:**
The Compton effect refers to the phenomenon observed when X-rays or gamma rays are scattered by matter, resulting in an increase in the wavelength of the emitted radiation. This effect demonstrates the particle nature of light, indicating that photons can collide with electrons and transfer energy, which leads to a change in wavelength.

**2. Explanation of the Compton Effect:**
- When a photon (X-ray or gamma ray) strikes an electron in a material, it can scatter off the electron.
- During this collision, some of the energy of the photon is transferred to the electron, causing the photon to lose energy and thus increase in wavelength.
