The photoelectron is emitted in the opposite direction to that of the direction of the incident photon, and does not violate the conservation of momentum. The conservation of momentum is based on Newton's third law which says that the forces acting during collision are equal and opposite. Thus, during collision of photon and electron, the photoelectron is emitted in the opposite direction.

Assertion: In an experiment on the photoelectric effect, a photon is incident on an electron from one direction, and the photoelectron is emitted almost in the opposite direction. It violates the principle of conservation of linear momentum.
Reason: It does not violate the principle of conservation of linear momentum.
Explanation:
The photoelectric effect refers to the phenomenon in which electrons are emitted from a material when it is exposed to light of a certain frequency or higher. The effect can be explained by considering the interaction of photons (particles of light) with electrons in the material.
Assertion Explanation:
When a photon strikes an electron in the photoelectric effect, it transfers its energy to the electron. If the energy of the photon is sufficient to overcome the work function of the material, the electron can be ejected from the material as a photoelectron. The direction of the photoelectron's emission is determined by the interaction between the photon and the electron.
Reason Explanation:
The assertion claims that the photoelectron is emitted almost in the opposite direction to the incident photon, which suggests a violation of the principle of conservation of linear momentum. However, this is not the case.
Explanation of the Principle of Conservation of Linear Momentum:
The principle of conservation of linear momentum states that the total momentum of a system remains constant if no external forces act on it. In other words, the initial momentum of a system is equal to the final momentum of the system.
Explanation of the Conservation of Linear Momentum in the Photoelectric Effect:
In the photoelectric effect, the photon carries momentum due to its particle-like nature. When it interacts with the electron, it transfers its momentum to the electron. The photoelectron is then emitted with a momentum equal in magnitude but opposite in direction to that of the incident photon. This conservation of momentum ensures that the total momentum of the system (photon + electron) remains constant.
Conclusion:
The reason correctly explains that the principle of conservation of linear momentum is not violated in the photoelectric effect. The emission of the photoelectron in the opposite direction to the incident photon is a result of the conservation of momentum. Therefore, the correct answer is option 'b' - both the assertion and reason are correct, but the reason is not a correct explanation of the assertion.
