A water tank appears shallower when it is viewed from top due to – (1) rectilinear propagation of light (2) reflection (3) total internal reflection (4) refraction

Description : A water tank appears shallower when it is viewed from top due to – (1) rectilinear propagation of light (2) reflection (3) total internal reflection (4) refraction

Last Answer : (4) refraction Explanation: This phenomenon is because of refraction of light. The lines of sight intersect at a higher position than where the actual rays originated. This causes the water to appear shallower than it really is.
