statement I: The intensity of a plane progressive wave does not change with change in distance from the source.
Statement II: The wavefronts associated with a plane progressive wave are planar.

A

Statement I is true, statement II is true and statement II is the correct explaination for statement I.

B

Statement I is true, statement II is true and statement II is NOT the correct explaination for statement I.

C

Statement I is true, statement II is false.

D

Statement I is false, statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
