Question:
In Huygens construction, the secondary wavelets move ________.
In Huygens construction, the secondary wavelets move ________.
Show Hint
The new wavefront is the forward envelope of these secondary wavelets.
Updated On: Jun 26, 2026
- in all directions
- only radially outward
- only radially inward
- only in the backward direction of the incident light
- in a direction perpendicular to the direction of the incident light
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Huygens' Principle states that every point on a wavefront acts as a source of secondary spherical wavelets.
Step 2: Meaning
A point source emits waves that propagate spherically.
Step 3: Analysis
These wavelets spread out from the point of origin in every possible direction.
Step 4: Conclusion
The secondary wavelets move in all directions. Final Answer: (A)
