Question

Question 8 (1 point)
Ms. Knuth places a stick in a pond. When she looked down at the stick, it appeared to be broken or bent at the point where the stick entered the water. This was caused by:

a
Reflection of light waves passing from air into water.
b
Refraction of light waves passing from air into water.
c
A refraction of light from the water.
d
Diffraction of light waves around the stick.

Answer 1

b

This is refraction: light changes speed and direction when it passes from air into water, making the submerged part of the stick appear shifted (bent) at the water surface.
