both filled to height h in the vessel of length 2h. one has refractive index root 2 and the bottom fluid has refractive index n. find the apparent depth of vessel.
n = real depth/apparent depth
The Attempt at a Solution
what these guys have done :
apparent depth = d/sqrt(2) + d/n
I don't get it, how do you add depths like these esp. when refraction happens at medium n and medium sqrt(2).?
