Given below are two statements:
Assertion (A): | It is not possible to have interference between the waves produced by two violins. |
Reason (R): | For interference of two waves the phase difference between the waves must remain constant.Given below are two statements. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
