what is the basic difference between compton effect and photoelectric effect?
479169
2 Answers. Photo electric effect occur in bound electron, while compton effect occur in free electron. In photo electron effect, the photo and hence energy of the photon is absorbed by the electron. While in compton effect photon is scattered.

There are mainly three laws of photoelectric emission: (i) The photoelectrons are emitted from the metal surface only when incident light has an adequate amount of energy. (ii) In photoelectric emission, the number of photoelectrons emitted per second is always directly proportional to the amount of the incident light.

In radiation: The photoelectric effect. The photoelectric threshold frequency, symbolized by the Greek letter nu with subscript zero, ν0, is that frequency at which the effect is barely possible; it is given by the ratio of the work function symbolized by the Greek letter psi, ψ, to Planck's constant (ν0 =…

E-beam irradiation is very similar to gamma radiation sterilization as being an ionizing energy but the difference is its high dosage rates and low penetration. Another difference is the use of e-beams which has a source of electricity producing high charge of electrons.

Gamma radiation consists of particles shooting out from the nucleus, where light are waves. Gamma radiation is also an electromagntic radiaton as light is, however, at a much higher frequency O Gamma radiation is also an electromagntic radiaton as light is, however, at a much longer wavelength..

The wavelength and frequency of light are inversely proportional to each other. Ex) wave length of light increases= the frequency decreases. ... The light emitted by an electron moving from a higher to a lower energy level has a frequency directly proportional to the energy change in the electron.

Both gamma radiation and visible light are electromagnetic radiation and are, in that sense, variants of the same thing. Gamma rays just have much higher frequencies. ... Also, gamma rays can be emitted when particles and antiparticles, such as an electron and a positron, meet and annihilate each other.

l = hc/E. A photon with an energy of 10.2 eV has a wavelength of 1.21 x 10-7 m, in the ultraviolet part of the spectrum. So when an electron wants to jump from n = 1 to n = 2, it must absorb a photon of ultraviolet light.

Explanation: X-rays and Gamma rays have shorter wavelengths than ultraviolet radiation.

Work function and threshold frequency are two terms associated with the photoelectric effect. The photoelectric effect is a widely used experiment to demonstrate the particle nature of waves. Work function and threshold frequency are two terms associated with the photoelectric effect.

gamma rays are emitted by excited atomic nuclei. x-rays are emitted by excited electrons. gamma rays are smaller in wave length,higher in frequency,and carry on more energy than x-rays.

Compton earned the 1927 Nobel Prize in Physics for the discovery. The effect is significant because it demonstrates that light cannot be explained purely as a wave phenomenon.

X-rays are a very energetic form of electromagnetic radiation that can be used to take images of the human body. ... The only difference between them is their source: X-rays are produced by accelerating electrons, whereas gamma-rays are produced by atomic nuclei in one of four nuclear reactions.

Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

Gamma-rays are detected by observing the effects they have on matter. A gamma-ray can do a few basic things with matter. It can collide with an electron and bounce off it like a billiard ball (Compton scatter) or it can push an electron to a higher energy level (photoelectric ionization).

Gamma rays originate from the settling process of an excited nucleus of a radionuclide after it undergoes radioactive decay whereas X-rays are produced when electrons strike a target or when electrons rearrange within an atom.
