Detailed Solution
Download Solution PDFThe correct answer is option 1) i.e. Each point in a wavefront is a source of secondary waves.
CONCEPT:
Huygens' concepts of secondary wavelets:
- Huygen’s principle states that every point on the wavefront may be considered as a source of secondary spherical wavelets that spread out in the forward direction at the speed of light.
- The new wavefront is the tangential surface of all these secondary wavelets.
- Secondary sources start making their own wavelets, these waves are similar to that of the primary source
- It states that each point on a wavefront is a source of wavelets, which spread forward with the same speed.
- Wavefront: A wavefront is a surface or a line on which the disturbance at every point has the same phase.
- Wavelets: It is a wave-like oscillation with an amplitude that starts at zero, increases, and then decreases back to zero.
EXPLANATION:
- Huygens's principle states that each point on a wavefront is a source of wavelets, which spread forward with the same speed.
