# Question: What is Compton effect class 12?

Contents

Compton effect refers to the increase in the wavelength of photons (X-rays or gamma rays), due to their scattering by a charged particle (usually an electron). The impact has ended up being one of the foundations of quantum mechanics, which represents both wave and particle properties of radiation.

## What is Compton effect in physics class 12?

Compton Effect When a monochromatic beam of X – falls on a target containing free electrons. it is scattered. As a result, the electrons recoil and scattered radiation has wavelength longer than incident one. This effect is called Compton effect.

## What is Compton effect in modern physics?

Compton effect is a process in which x-rays collide with electrons and are scattered. Unlike the prediction of classical wave theory, the wavelength of the scattered radiation does not depend on the intensity of radiation but depends on the scattering angle and the wavelength of the incident beam.

## What is Compton effect Mcq?

Solution: When a photon collides with an electron at rest, the photon gives its energy to the electron. Therefore the scattered photon will have higher wavelength compared to the wavelength of incident photon. This shift in wavelength is called Compton shift.

## What is a photon Class 12?

They are minute packets of energy or quantum of energy which constitute the electromagnetic waves. Photons are always in motion and in the vacuum, travel at a constant speed of2.998×108msec−1. This is the speed of the light and it is denoted by the letterc. Einstein proved that light is the flow of photons.

## What type of photon is needed for Compton effect?

The Compton effect occurs for most of the atomic electrons. A gamma photon plays the role of a projectile that collides with an electron in an atom that serves as a target. Gamma was represented as a punctual particle because of its very short wavelength at the atomic scale.

## What is photon and its properties Class 12?

The basic properties of photons are: (1) They have zero mass and zero rest energy. They only exist as the moving particles. (2)They have no electric charge. (3) In the empty space, they travel at the speed of light.

## Is an electron a photon?

Photons are massless and carry no electromagnetic charge. Electrons have mass and charge, so they are fundamentally different particles. Electricity is the flow of electrons. Light is emitted when electrons change states in their atom, from higher energy states to lower.

## Does Compton depend on material?

The probability of a Compton scatter event occurring in a given material depends directly on the scattering cross section and on the electron density of the material (the electrons represent the scattering sites). The magnitude of the cross section is also dependent on the energies of the incident photons.
