Question

The diagram below shows a light ray striking Medium A and Medium B at the same angle.

A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.
Which statement is correct?

The speed of the light ray is the same in air and in Medium A.
The speed of the light ray is the same in air and in Medium B.
Medium A is denser than Medium B because light bends more in Medium A.
Medium B is denser than Medium A because light bends more in Medium B.

Answer 1

Answer: D Medium B is denser than Medium A because light bends more in Medium B.

Explanation: The more the light bends the less energy it has
