Question

At left is an empty glass with a straw in it. From the options, identify the correct view of the straw when the glass is half-filled with water.

• A. A
• B. B
• C. C
• D. D

Hint:

Light bends away from the normal when exiting water; objects under water look shallower and lines crossing the surface appear “broken” at the interface.

Answer 1

The Correct Option is A

Refraction at the air–water interface makes the submerged part of the straw appear bent at the water line and shifted, with the underwater segment looking closer to the normal (more vertical) and slightly raised.
Among the options, only (A) shows a kink at the water surface with the immersed part appearing steeper than the portion in air.
Therefore the correct representation is \(\boxed{\text{(A)}}\).
