The
purpose of this lab is to measure wavelengths of different light sources using
a device called a spectroscope. I have provided sample pictures containing the wavelength
measurements of the following light sources taken with a camera through a
spectroscope.
Wavelength measurements are measured by
nanometers (nm) (x10^9). The purpose of measuring wavelengths is used to
specify the strength of the colors measured by their peaks to relate to
specific elements on the periodic table of elements. Each element has its own
wavelength frequency, and by using a spectroscope you are able to identify
which element is present. Astrophysicists and space explorers use this in search
of planets for inhabitability and resources. If a planet contains too many
poisonous gases it would be identified using spectroscopy and we would better
know to avoid landing on those planets or sending humans to explore those
planets.1. Scattered Sunlight
