the light is travelling in a straight path. However, for most light sources the path is difficult to see. This is because most light sources are so bright that you can not see a single ray of light. Today’s investigation is designed to show that light does indeed travel in a straight line. Equipment: 4 index cards Play clay Ruler

Light is a form of energy that allows us to see things. It is made up of tiny particles called photons. Light travels in straight lines and at a very fast speed.
Sound is a form of energy produced by vibrations. These vibrations travel through the air as sound wavesand can be heard by our ears.
Light and sound can both be absorbed, reflected, or refracted. For example, when light hits an object, it can be absorbed or reflected, and when sound waves encounter different materials, they can be absorbed or reflected as well.
Here are some key points to remember: 1. Light is a form of energythat allows us to see things. 2. Sound is a form of energyproduced by vibrations. 3. Light travels in straight lines and at a very fast speed. 4. Sound travels as wavesand can be heard by our ears. 5. Both light and soundcan be absorbed, reflected, or refracted.
Experiment: 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.
