+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Due to reflection it reverses ur wave ie add pi in path diff
it happens only in the case when ray moves from rarer to denser but no phase or path difference wave travels from denser to rarer so intuitively what's special on moving from rarer to denser?
@SIMPle Potato
Rarer to denser? Its a mirror why would medium matter imagine a wave refelection it will reverserd after reflection from a surface

if initial eqn of wave is y = sin(wt-kx). from free end final eqn becomes y=Asin(wt+kx) and from rigid end it becomes y= -Asin(wt+kx)
This is what I was thinking that if there's a reflection why λ/2 is added

This is what I got @SIMPle Potato
But I think it's derivation is the part of Engineering curriculum, if you get to know about it in your college , do mention the reason in simplified version if possible then... @SIMPle Potato
Put phi = pi and you get the lambda/2
I think for mirror it should be clear why wave is reflected
For refraction, you can get little better understanding from here but idk about that either https://youtu.be/KTzGBJPuJwM?si=6Uwy8z6qa16Wiq4-
