When immersed in a beaker of water, a straight glass rod seems to undergo bending, as depicted in the diagram.

Question

What provides the most accurate explanation for this phenomenon?

Responses

At the interface between air and water, light undergoes reflection.
At the interface between air and water, light undergoes reflection.

The temperature of the water in the beaker is higher than that of the surrounding air.
The temperature of the water in the beaker is higher than that of the surrounding air.

As light crosses the boundary between air and water, it undergoes refraction.
As light crosses the boundary between air and water, it undergoes refraction.

In water, light moves at a higher speed compared to its velocity in air.

Answer 1

The most accurate explanation for the bending of the glass rod when immersed in water is:

As light crosses the boundary between air and water, it undergoes refraction.

This is because refraction occurs when light travels from one medium to another (in this case, from air to water), causing a change in its speed and direction, which is responsible for the apparent bending of the rod.
