Hi Guys,
I am new to this forum and have a "quick" question.
Say you had a laser pointer and you directed the laser through a glass block and then to a LDR why would the light intensity recorded be lower than without the glass block? What is happening to the light when it is in the glass? And why does making the glass thicker make the light intensity decrease even more?
Thanks a lot.
Oli.
