For diffraction at a single-slit the angular width of the principal maximum is inversely proportion to the width of the slit i.e., angular width θα 1/a . Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.
No, reduction in speed on passing from a rarer to a denser medium does not imply a reduction in energy of light because the frequency of light remains unchanged and the energy of a light photon depends only on its ...
(i) Two sources must emit light of same wavelength (or frequency). (ii) Originating phase difference between two light sources must be either zero or having a constant value, which should not change with time. Class 12 Physics Chapter 10 Wave ...
Yes, law of conservation of energy is strictly followed in interference phenomenon. Of course there is redistribution of energy but there is no net loss or gain of energy in accordance with the conservation law of energy. Class 12 Physics ...
