Blackbody radiation: a spectroscopic study John Greavu Partner: Nicholas Souhleris TA: Yilikal Ayino (Friday‚ Section 006) April 18‚ 2014 I. PRELAB A blackbody is a body that absorbs all electromagnetic radiation and emits a continuous spectrum‚ such as heated cavern with just a small opening to the outside world. In 1900‚ German physicist Max Planck derived an expression for this blackbody spectrum. Knowing that oscillators emit radiation‚ he assumed that oscillators within the cavern were

3.1 CATHODE RAYS 3.1.1 Explain that cathode ray tubes allowed the manipulation of a stream of charged particles. DEFINITTIONS: * Cathode Ray Tube: is an evacuated tube which allows the unobstructed movement of cathode rays from a cathode to an anode. * Cathode Ray: Are negatively charged particles and can therefore be deflected. * This can be shown by 3 facts: * They leave –ve charge on the surfaces they strike * They are deflected by magnetic fields as predicted

related phenomena due to the interference of light. 0 Time Christiaan Huygens (~1678) considered light as a wave. Using a wave model he was able to explain all the known phenomena of light mentioned above as well as interference and diffraction of light. Constructive interference results in greater amplitude The dark bands are formed when the two waves arriving at the screen are half a cycle out of phase‚ i.e. wave crest combines with wave trough. This is called destructive interference

Introduction For the past two decades or so‚ television shows‚ books‚ and movies that portray detective work and forensic science have become increasingly popular among readers and enthusiasts. They demonstrate that science is an important tool in answering difficult questions regarding how the tragic assassination of President Kennedy happened for example. Forensic Science is appealing to many people because they want to be detectives to solve problems and puzzles. Today I will focus on how scientific

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the
