In Young's double slit experiment, using monochromatic light of wavelength λ$\lambda$ , the intensity of light at a point on the screen where the path difference is λ$\lambda$ , is K units. The intensity of light at a point where the path difference is (λ)/(3)$\frac{\lambda}{3}$ will be

In interference and diffraction, the light energy is redistributed. If it reduces in one region, producing a dark fringe, it increases in another region, producing a bright fringe. A. As there is no gain or loss of energy, these phenomena are consistent with the principle of conservation of energy. B. Diffraction and interference are characteristics exhibited only by light waves. Choose the correct answer from the options given below:
