An Ocean Optics Photodiode Array was used to compare the wavelengths emitted from green and red lasers. A green and a red laser passed through a green and a red filter, respectively. The wavelength of red light ranges from approximately 635-700 nm and the wavelength of green light ranges from approximately 520-560 nm. However, this data shows another peak around 800 nm from the green laser. This is because of how a green laser works, which involves a three step process. A standard laser diode initially gives a wavelength of 808nm, which is focused on a neodymium crystal that converts the light into infrared with a wavelength of about 1000 nm. Finally, the light goes through a frequency doubling crystal that emits green light with a wavelength of 532 nm.

A green and a red laser were shone (separately) through a green and a red filter, respectively. The wavelength of red light ranges from approximately 635-700 nm and the wavelength of green light ranges from approximately 520-560 nm.

Welcome to the Light lab.

In the introductory chapter we were exposed to a series of experiments that were not appropriately described by the current theory, ie. classical mechanics. These experiments lead to the development of quantum mechanics. Many of these experiments involved "light." In this lab activity we will explore light at a deeper level.

==Introduction==
- Review of emission spectra using the photodiode array detector, including Rydberg equation.
