Spectrograph

This is the final product that you are looking for, a spectrograph that helps us see light spectrums that the naked eye can´t.

Before starting this DYI (do it yourself) experiment you need to read this concrete directions that will help us later to build our spectrograph.

After reading the instructions from the last step, these are all the materials you need to build the spectrograph, in my case, I recommend using a black cardboard (as the one shown in the photo), and an only side cd for it to much easier to manage for the lens of your product.

After finishing your spectrograph, you are going to check the results with three different types of light bulbs, first, you are going to test how your spectrograph reacts to the light of the circular bulb, and as you can see in the images, the ray bust appear as a straight line, this is the incandescent light. On the other side of the coin, you have either the red or white fluorescent bulb, which must show many rays in straight lines next to each other.
