Question

the depth of water in a vessel when seen from air appears to be less.explain​

Answer 1

• This is due to the phenomenon of refraction.
• As the light passes from the bottom of the vessel through water (dense medium) to air (rarer medium), it gets refracted.
• The light thus bends away from the normal (perpendicular).
• Hence, the bottom of the vessel appears to be raused, that is, the depth of water appears to be less.
