Lights & Beautiful Colors

This week in physics we began a new unit which covers information on electromagnetic waves/color. Electromagnetic waves are capable of going through a vacuum, they are produced by a vibrating charge. These waves exist with a range of different frequencies. You can analyze these different waves and frequencies on a thing known as the electromagnetic spectrum. By now it is common knowledge that lower frequencies have longer wavelengths and vice versa.

I have inserted this image from google that shows the different frequencies. It also compares the visible light spectrum. This diagram can show us the different types of color that can be seen. Light refers to a type of electromagnetic wave that stimulates a part of our eyes known as the retina. Each wavelength within the spectrum of visible light has a specific color so that when light of that wavelength hits our eyes we can see color. In class this past week we discussed different types of visible light and we were able to use laser pointers to try and analyze different colors. When all the wavelengths of the visible light spectrum hit our retinas they come together to form white. White is the result of all the colors mixed together. We also learned that black is just simply the absence of color and light. Here are some images from class: 

Here you can clearly see the red light because it is part of the visible light spectrum. It was hard to get this picture because our camera lens does not work the same way as our eyes with picking up light and such.
