MCAT RESOURCES & INFO Study Groups What happens when there's way more then two holes Created by David SantoPietro. Want to help us improve this subreddit or tell us about a new resource we can add to the sidebar? 820K views 9 years ago Light and Electromagnetic Radiation. This means that a microscope using electron 'matter waves' instead of photon light waves can see much smaller things. Below you will find our forum rules, resources, and more. Since electrons have a rest mass, unlike photons, they have a de Broglie wavelength which is really short, around 0.01 nanometers for easily achievable speeds. We request that you read the sidebar COMPLETELY before you post. r/MCAT is a place for support, discussion, advice, social networking, news, study tips and more. Hertz used a spark gap (two sharp electrodes placed at a small distance so that electric sparks can be generated) to detect the presence of electromagnetic waves. The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical schools in the USA and Canada. It was in 1887 when Heinrich Hertz was conducting experiments to prove Maxwell’s electromagnetic theory of light, that he noticed a strange phenomenon. The refractive index is used in (not defined by) Snell's law, which relates the angle of incidence to the angle of refraction when light passes from one material into. where c is speed of light in vaccum, and v is velocity of light in the material. Welcome to the BEST place for MCAT prep and practice materials. The refractive index tells you the speed of light in a given material.
