NEET Physics Huygens Principle Assertion Reason Question
Assertion (A): A wavefront is defined as a surface of constant phase.
Reason (R): The speed of the wavefront is the same as the speed of the wave in the medium.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
Assertion is true as a wavefront is indeed a surface of constant phase, and the reason is true because the speed of the wavefront is the speed of the wave, but the reason does not explain the definition of a wavefront.
