Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but ...

Sunlight reaches the earth as white light, which is made up of all the rainbow colors. Rainbow colors are red, orange, yellow, green, blue, indigo, and violet. It is easy to remember them by using the ...

Learn about color and how to create a spectroscope using simple materials. What is color? Learn about light and wavelengths and what creates color in this episode of Camp GPB. Then learn how to build ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...
