O'ptikada qo'shimchalik tamoyili explains the interference phenomenon of light waves. The main concepts are interference and superposition. Interference occurs when two or more light waves overlap, resulting in either reinforcement or cancellation of light intensity. Superposition is the mathematical sum of these waves, leading to the formation of resultant light waves based on their phase and amplitude. Constructive interference occurs when waves are in phase, while destructive interference occurs when they are out of phase. This concept is crucial in optical devices and experiments
