Explanation:

The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics and in fields of chemistry such as quantum chemistry and electrochemistry.

According to classical electromagnetic theory, the photoelectric effect can be attributed to the transfer of energy from the light to an electron. From this perspective, an alteration in the intensity of light induces changes in the kinetic energy of the electrons emitted from the metal. According to this theory, a sufficiently dim light is expected to show a time lag between the initial shining of its light and the subsequent emission of an electron.

Answer 2

$\huge\bf{Answer:-}$

• When a substance metal and nonmetal solids, liquids and gases emits electrons after absorbing energy from an electromagnetic radiation such as X-rays, visible light, etc , it is called photoelectric effect.
