Explanation 1) Concept: Here, we need to use the equation of conservation of energy. The incident energy of photon should be equal to the scattered energy of photon and the kinetic energy gained by the target material. 2) Formula: i) E i = E f + K 3) Given: i) Figure 38.21 of graph of K vs angle ϕ . ii) The energy gained by target material is K. 4) Calculations: Let us consider the collision of a photon and the stationary free electron, which gets scattered after collision. According to the conservation of energy, we can write E i = E f + K where, E i is the initial energy of photon

Particle Theory of Light

The particle theory of light was the proposal made by Newton in 1704 in his treatise Opticks. This is the most basic light theory, in which light is thought to be made up of microscopic particles known as "corpuscles" and that's why this particle theory …

Stopping Potential

In an experiment conducted by Heinrich Hertz, an apparatus was made where the incident light was made to fall on the metallic plate, it was discovered that metals emit electrons. The surface electrons are bound to metals with a minimum amount of energy a…

Quantization of Charges

An electron is a negatively charged subatomic particle either attached to an an atom or sticks to the nucleus of the atom. Electrons exert the negative charge that tries to balance the positive charge of the nucleus.

tionary free electron gains when a photon scatters from it. We can plot K versus the an- gle o at which the photon scatters; see curve 1 in Fig. 38-21. If we switch the target to be a stationary free proton, does the end point of the graph shift (a) upward as suggested by curve 2, (b) downward as suggested by curve 3, or (c) remain the same? 3. 180° Figure 38-21
