can you derive the meaning of underline part that if they are constant means value is not changing then how they are not same???

so hope you will get to know the difference between same phase and constant phase. coherent waves have constant phase difference not same phase.

If you have any doubt feel free to comment.

assume two waves, sin(wt) and sin(wt+c), where 'c' is constant. here the two waves have same frequency (w) and their phase difference is (wt+c - wt = c) constant. I guess the point...

When the two quantities have the same frequency, and their maximum and minimum point achieve at the same point, then the quantities are said to have in the same phase. while phase ...
Suppose A and B are two sources of light. If two sources are in same phase then phase difference between them is zero. To be the coherent source condition is the difference in pha...

like sin and cosine waves are suoerposing thay have phase difference as we know if their phase doesn't chamge with time they are coherent.but perfe coherence hard tk find so we tak...

and dear it's defination or say property of coherent beams.
• Dhairya sharma
yes dear coherent means like 2 have phase difference at pi then with respect to time if they remain at same phase they are called coherent. coherent means phase difference will not...
