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.

Update on Energy Project

So basically, this week my blog post is dedicated to updating you all on my project and how it is coming along. I have mentioned before that my project was based on stopping the use of my dryer and hoping to see some type of decrease in my energy bill. This week has been my second week or so of keeping up with my experiment. The ironic part in this all, is that my dryer actually broke a few days ago therefore there is no option but to actually hang out clothes. I must say it is really not that hard to hang laundry onto a clothes line. So far there are many lessons that I have learned throughout this project. For example, it is good to save money but it takes actual effort to save a few bucks. Another thing I learned from this project is how easy we have it these days. We have machines to do everything for us, from washing dishes to drying clothes. Drying clothes is a task that can done freely by using the power of the sun. I often wonder why we pay money to complete a task when it can be done for free?
Here I inserted a picture of the sun, to remind us how beautiful it really is and how much money it can save us on our energy bills. So far throughout this experiment I have realized how useful of a tool this is, and it really is so valuable. Hopefully at the end of this experiment I can fully appreciate the greatness of the sun and find/discover a way to use it to it's full potential.
