The emission of electrons from a metal surface when exposed to light of suitable frequency is known as:
Correct answer: B. Photoelectric effect
- A. Compton's effect
- B. Photoelectric effect
- C. Coulomb's effect
- D. Faraday's law
- E. Ohm's law
Explanation
The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons.The correct option is B.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
