What is path length difference?

Click For Summary
SUMMARY

Path length difference refers to the difference in distance traveled by two waves or secondary wavelets, particularly in the context of integrals and physics. This concept is crucial for understanding interference patterns, where the path length difference can affect the resulting wave interactions. The discussion emphasizes the importance of context when applying this term, particularly in mathematical and physical scenarios.

PREREQUISITES
  • Understanding of integral calculus

My text keeps referring to it but I have no idea what it refers to.

Depends on the context. But in the context of integrals, you can often have your integration follow different paths for the convenience of the math.
 
In physics when studying interference patterns it is simply the difference in distance traveled between two waves or secondary wavelets/
