Lesson Transcript
Instructor: Christina Paulk

Christina has taught K-8 and has a master's degree in education.

Light is something that we do not always pay attention to, but we sure miss it when it is absent. It keeps us warm and helps us see the world. This lesson will explore light as an important energy source.

What Is Light?

Imagine you're in a dark room. You aren't able to see anything. Your eyes need light to see. Even the smallest amount of light helps your eyes view the world. Did you know your eyes can detect the flame of a candle on a dark night about a mile away? You would think that the light from that candle moves in a straight line from the flame to your eyes, but a beam of light is actually an energy source that travels as a wavelength, and it moves quickly.

Now, imagine you're outside and it's been raining. You look up in the sky and see a beautiful rainbow. When the white light from the sun hits rain droplets in the sky, the wavelengths separate into the different colors of the rainbow. Each color is a different wavelength. Our eyes can see these wavelengths of light, and our bodies can feel the warmth from the sun.

What Are Sources of Light?

Light is a form of energy that helps us to see all the things around us. Light can come from different sources. Let's look at some of these sources now.

Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms. This is called bioluminescence.

Artificial light is created by humans. Flashlights, table lamps, neon signs, and televisions are some sources of artificial light. Most of the lights that are man-made need an energy source, such as electricity or batteries, to produce light.
