Question

Which example involves the transformation of chemical energy directly into light energy?

A) a wind mill
B) a glow stick
C) photosynthesis
D) a hydroelectric dam
(I'm pretty sure it's b, but just want to make sure)

Answer 1

B

Step-by-step explanation:

A glow stick involves the transformation of chemical energy into light energy. The chemical energy is stored.

Answer 2

Yes, you're right, it's a glow stick!

a glow stick has two substances in it, which are separated from each other and breaking of the glow stick makes them combine and release energy in the form of a light. This process is also known as chemiluminescence. They don't require any other energy sources!
