Which of the following is an example of the refraction of light? a. light transforms a substance through absorption. b. light passes through an object unchanged. c. light bounces off of an object's surface. d. light bends as it passes from one medium into another.

D

Explanation:

When light bends as it passes from one medium into another, it is refraction.

Refraction is known as the change in direction of a wave passing from one medium to another caused by its change in speed.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
