Read The Experiment to Learn How Light Travels
How Does Light Travel?
Light travels in a straight line, and it travels fast—about 300 000 km/s. One way you can tell that light travels in a straight line is shadows. If you stand with your back to the Sun, your body will block the light. So the shadow you see in front of you is the space where no light is getting through. Here is another way to check that light travels in a straight line.
- A flashlight
- Some flour in a cup
- A partner
