How to do it!

Sunlight or white light is a mixture of all the rainbow colors. The different rainbow colors are essentially mixed together to result in a white color. You may wonder why when you mix all the different colors of paint together result in black instead of light. That is because light mixing is additive while pigment mixing is subtractive. When light passes from one medium to another medium of a different density e. How much a light is refracted depends on the wavelength of the light.

The shorter the wavelength, the more it bends. Because lights of different colors have different wavelengths, each color is refracted by different amounts. Therefore, white light is split up after passing from air to water and the individual colors become visible. In nature, a rainbow is formed when sunlight is refracted on entering a droplet of water, reflected inside the back of the droplet and finally refracted again on leaving the droplet. To see a rainbow caused by sunlight, the sunlight needs to come from behind us because rainbows only appear in the part of the sky directly opposite the sun.

Red has the longest wavelength among the visible colors. So it tends to bend the least and the angle between the incident light and our line of sight for red is approximate 42 degrees. As a result, red appears on the top of the rainbow. Violet has the shortest wavelength. It tends to bend the most. To see violet, the angle between the incident light and our line of sight is roughly So violet appears at the bottom of the rainbow. Rainbows are not two dimensional. A rainbow is seen at an angle that is between degrees from the incident sunlight.

So all the water drops that produce each color in the rainbow lie on a three dimensional cone. Our eyes are at the tip of the cone. Now are you ready to make some rainbows? Here are 3 easy ways to make your own rainbows at home. Warning: Adult supervision is vital in experiments involving sunlight. Do not look directly at the sun or at the reflection of sun in a mirror. One of the easiest and most visually stunning ways to see a rainbow is by using a prism.

Prism rainbow looks stunning. No prism? No problem. Using a small mirror and a glass, you can make a beautiful rainbow on the wall. You can still make a rainbow without natural light. Try this experiment using a whitelight flashlight. This mulitple award-winning science kit is educational and fun.

There are many hands-on rainbow experiments. You can wear rainbow glasses, design a rainbow spinner, blow rainbow bubbles, make rainbow milk, bend white light, mix colored paddles and much more.

Highly recommended for budding scientists and rainbow lovers. Still have questions about rainbows? This is the book you should get! It explains everything about rainbows from colors to positions to the arc shape in a way that even my 3 year old was able to understand. It is informative but not too technical for little kids to understand the concepts. This is an excellent book that teaches about light. Through simple and clear illustrations, you can learn to make reflections, shadows, and rainbows.

Great addition to a classroom library for preschool through 2nd grade and can supplement the Light and Shadows unit. By accessing the science activity ideas on Rookieparenting.

Active Time: 15 minutes. Total Time: 15 minutes. Materials strong sunlight. Instructions Place a piece of white paper on the ground under the sunlight. Put the prism on or above the paper. Rotate and move the prism around until you see rainbow colors on the paper. Materials water sunlight.

Tools a clear glass small mirror adult supervision. Instructions Fill the glass with water. Put the mirror into the water inside the glass at an angle. Position the glass so that sunlight shines directly at the mirror. You may have to shift the mirror to find the right angle.

Look for a reflection on the wall. It would be easier to see if the room is dark. Adjust the angle of the mirror until you see a rainbow on the wall. Active Time: 30 minutes. Total Time: 30 minutes. Materials water. Tools clear glass flashlight that emits strong focused white light. Look for one with parabolic reflecting mirrors inside to focus the light, or one with a strong LED light. Cut a narrow rectangle in the middle of one piece of paper. Stick that paper to the outside of the glass so that the slit is at the center.

Place the other piece of paper on the floor on the other side of the glass to catch the rainbow. In a pitch dark room, point the flashlight at the slit. Start from the glass and slowly move the flashlight farther and farther from the glass. Adjust the distance and angle of the flashlight until you see a rainbow on the paper on the other side.
