Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations? (2 points) a
Since glass is translucent, most of the light energy was reflected from the glass. When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.

b
The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.

c
The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.

d
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
