No. Reduction in speed of light has no connection with energy carried by light wave. Energy carried by a wave depends only on its amplitude. Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.
Reflection and refraction both arise through interaction of incident light with the atomic constituents of matter. Atoms may be considered as oscillators which vibrate with the frequency of light. The frequency of light emitted by a charged oscillator equals its ...
A wavefront is defined as a surface of constant phase. Consider a plane surface XY separating a denser medium of refractive index n₁ from a rarer medium of refractive index n₂. Let c₁ and c₂ be the values of speed ...
The conservation law of energy holds good for the phenomenon of interference as well as diffraction. Due to interference or diffraction we obtain maxima and minima intensities at different points. From points of minima intensity the energy has been shifted ...
