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.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
