Hey, I'm doing a science demo in front of a bunch of sixth graders (I'm in 8th grade) and I am taking a mirror and then two tubes angled into the mirror- with a flash light shining into one. The reflection of the tube with the flash light is lined up exactly with the other tube. The light then shines out of the reflection and in and out of the second tube. It sounds really confusing but it's actually cool. So, my teacher says I need to explain how light travels in straight lines and light energy and stuff. So I need help! Thanks
light travels straight that`s the property of electromagnetic wave about the light energy it needs energy to travel
