A wavefront is the locus of points vibrating in phase, representing the crest of a wave at a given time. Using Huygen’s principle, each point on the wavefront acts as a secondary wavelet source. At a boundary between two media, constructing tangents to these wavelets shows how wave direction changesRead more
A wavefront is the locus of points vibrating in phase, representing the crest of a wave at a given time.
Using Huygen’s principle, each point on the wavefront acts as a secondary wavelet source. At a boundary between two media, constructing tangents to these wavelets shows how wave direction changes, verifying Snell’s law: sin i/sin r = v₁/v₂ .
In the photon picture of light, intensity is determined by the number of photons per unit area per unit time. Higher photon flux corresponds to greater intensity because each photon carries a discrete amount of energy, proportional to its frequency (E = hν). For more visit here: https://www.tiwariacRead more

No, the reduction in speed does not imply a reduction in energy. The energy of a light wave depends on its frequency (E = hν), which remains unchanged when light enters a denser medium. Only the wavelength and speed are affected, not the energy. For more visit here: https://www.tiwariacademy.com/nceRead more

The frequency of light remains constant during reflection and refraction because it is determined by the source and cannot change at the boundary. A change in frequency would disrupt the continuity of the electromagnetic wave, violating energy conservation. Only the wavelength and speed adjust in thRead more
The frequency of light remains constant during reflection and refraction because it is determined by the source and cannot change at the boundary. A change in frequency would disrupt the continuity of the electromagnetic wave, violating energy conservation. Only the wavelength and speed adjust in the new medium, ensuring the wave’s frequency remains unchanged in both cases.

Explain the following giving reasons : In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. What determines the intensity of light in the photon picture of light?
In the photon picture of light, intensity is determined by the number of photons per unit area per unit time.

Explain the following giving reasons When light travels from a rarer to a denser medium, the speed decreases. Does the reduction in speed imply a reduction in the energy carried by the light wave?:

Explain the following giving reasons : When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency. Explain why.
