Question 2 • (AG Q3) Physical Science: 25-26 (JComunale)

Which best describes what happens when light traveling through air enters water at an angle?

Answer
A
It moves along straight lines in air and changes direction when it enters water.
B
It moves in a curve in air and moves in straight lines when it enters water.
C
It moves along straight lines in air and continues along the same lines when it enters water.
D
It moves in a curve in air and continues moving in the same curve when it enters water.

Explanation

Light travels in straight lines through a uniform material such as air. When it enters water at an angle, its speed changes, causing it to bend and change direction; this is called refraction. Therefore, the best description is that it moves in straight lines in air and changes direction when it enters water.
