Hey, well I finally got an idea for my project which is on color and lightwaves they send out. Can someone provide some information about light wave lengths and interesting facts about it. thanks!

Lightbulb Rainbow!

Visible light wves are the only electromagnetic waves we can see. We see these waves as the color of the rainbow. Each color has a different wave length, red has the longest while violet has the shortest. When all of them are seen together they form white light.

Hope this was a little help

Default Color

Color is just light. For example, take an apple. The apple is red. the skin of the apple absorbed in all other light but the red colored kind. So the red color is the one being reflected, not absorbed. Alot of people get that confused.

Lightbulb wow!!!!

I never knew that.
I always thought that the apple absorbed the red light

Thanks for correcting me

P.S. Merry christmas to all and to all a good night!

Talking Well

In a rainbow, red is the top color because it has the longest wave length of the colors. In turn, purple has the smallest.

I know that white light can be broken up into different colours where as laser light is only one colour

Default Refraction of light

What Rachael is referring to is Refraction, I believe.

When a beam of light enters a medium from vacuum or another medium, it keeps the same frequency and changes its wavelength. If the incident beam is not orthogonal to the edge between the media, the direction of the beam will change. Refraction of light by lenses is used to focus light in magnifying glasses, spectacles and contact lenses, microscopes and refracting telescopes.

If you try refracting a laser made up of just 1 color of light, it will not be "split" into different colors.
