Study Notes
Light and its Properties
- Light is produced when gasses burn, creating electromagnetic energy in the form of magnetic and electrical waves.
- The type of gasses burned determine the color of light emitted.
- Light behaves differently depending on the object it encounters.
Reflection
- An object must reflect light for it to be seen.
- Reflection occurs when light bounces off opaque objects (objects you cannot see through).
- Light from a light source travels to an object, reflects off the object, and then reaches your eyes.
Absorption
- Some light is absorbed by an object rather than reflected.
- Absorbed light waves are not visible to the human eye.
- The colors we see are determined by the light waves that are reflected, and not those that are absorbed.
- For example, a yellow blanket absorbs all colors except yellow, so it reflects yellow light waves.
Transmission
- Light can pass through transparent objects (objects that allow you to see through them).
- Transmission occurs when light waves pass through and out the other side of the object.
- An example of transmission is sunlight passing through a glass window.
