Light energy is converted into electrical energy in(a) Photosynthesis(b) Photoelectric cell(c) Photography(d) Photolysis

The correct answer is (b) Photoelectric cell.

In a photoelectric cell, light energy is converted directly into electrical energy. This process is based on the principle of the photoelectric effect, which involves the emission of electrons from a material when light of suitable frequency (energy) is incident on it. The emitted electrons can then be collected and used as an electric current, resulting in the conversion of light energy into electrical energy.

Photosynthesis, on the other hand, is a biological process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It is not a direct conversion of light energy into electrical energy.

Photography is the process of capturing and recording images using light. It involves the use of a camera and a photosensitive material, such as film or a digital sensor, to capture and store visual information. Although photography utilizes light, it does not directly convert light energy into electrical energy.

Photolysis refers to the chemical decomposition or splitting of a compound using light energy. It is often used in chemical reactions where light is used to break bonds and initiate chemical transformations. Photolysis does not directly convert light energy into electrical energy.
