Question

What is the difference between real depth and apparent depth?

Answer 1

Sr. No.	Real Depth	Apparent Depth
1.	It is the actual physical distance of an object from the surface of the liquid.	It is the virtual or perceived distance of the object from the surface.
2.	It remains constant and does not change based on the observer's viewing angle.	It changes depending on the refractive index of the liquid and the viewing angle.
3.	It is measured directly using a physical scale or a ruler.	It is an optical illusion caused by the refraction of light rays at the boundary surface.
