Compton effect

Compton effect expt. is carried out with

• x ray

• gama ray

• visible light

• heat waves

Compton scattering establishes

• photonic nature of electromagnetic wave

• wave nature of electromagnetic wave

• both wave and particle nature of electro magnetic

• electron is a matter

Elements of low atomic mass are preferred in Compton effect

• low atomic mass elements are easily available

• with low atomic mass coulombic attaraction is less and greater probability of making electron free

• with low atomic mass coulombic attaraction is high and greater probability of making electron free

• with low atomic mass coulombic attaraction is less and lesser probability of making electron free

Photonic energy of x-ray photon of wave lenght 0.1 A is

• close to 2 eV

• close to 2x 104 eV

• close 0.2 eV

• close to 2 x 102 eV

In Compton effect we use X-ray because

• it is easy to produce

• it has very small wave length

• x-ray photon has very high energy

• it is a X-ray diffraction experiment

The ratio of de Broglie wave length of a moving proton and moving electron is

• 2:1

• 1:2

• 1:1

• 3:1

Estimate de Broglie wave length of a photon moving with energy 100 eV and a electron moving under the electric field of 100 V.

• photon 120 Angstorm and electron 1.21 Angstrom

• photon 1.20 Angstorm and electron 121 Angstrom

• photon 120 Angstorm and electron 121 Angstrom

• photon 1.20 Angstorm and electron 1.21 Angstrom

Compton wave length is

• $\frac{h}{m0C}$

• $\frac{h}{mc}$

• $\frac{h}{\lambda C}$

• $\left(1-Cos\alpha\right)$

Compton Shift given by  $\Delta\lambda=\lambda c\left(1-Cos\alpha\right)$  becomes maximum at

• scattering angle equal to 90 degree

• scattering angle equal to 0 degree

• scattering angle equal to 180 degree

• scattering angle equal to 360 degree

Wave particle duality means

• a wave can show wave behavior

• a particle can show particle behavior

• a wave can some times show the property of particle

• a wave can some times show the property of wave and matter both
