In young's experiment, how must waves be vibrating to for interference to occur? a. in line b. in phase c. out of phase d. out of line

The answer is B. In Phase

Explanation :

The phenomenon of the superposition of two waves is called the interference of the wave.

For a stable and clear interference pattern, the conditions can be :

So, it is clear from the first condition that the waves must be vibrating in phase to occur interference.

Hence, the correct option is (b) "in phase".

i think the miocene epoch spans the time from 23 million to 12 million years ago.

c is the correct answer hope this !
