De Broglie began from Bohr’s equations which showed that (as a particle) the angular momentum of the electron would be a multiple of h/2π. Diffraction is something that only waves do. Barrier From this he was able to show that (when showing its wave properties) the electron would have a wavelength related to its mass and velocity: with gaps in it Parallel wave fronts approach the

Many people believe that DNA was discovered in 1950 by Watson and Crick‚ but they are misguided‚ in fact it was discovered almost centuries before by a number of less known scientists. Genes were discovered to be heritable from parents by a humble pea grower by the name of Gregor Mendel in 1866. Since then we have discovered that DNA‚ also known as deoxyribonucleic acid‚ is the carrier of genes‚ traits that pass down from generation to generation.The reality is that the credit didn’t go to everyone

Nature of Waves Vibrations or oscillations are closely related to waves. Waves are created whenever objects vibrate or oscillation. Periodic Motion * A repeated motion that occurs back and forth over the same path at regular intervals. Examples: * A Child on a swing * A wrecking ball swaying to and fro * A swinging pendulum of a grandfather clock Simple Harmonic Motion (SHM) * Is a type of motion along a straight path in which the acceleration is proportional to the displacement

Structural Analysis of Serine Peptidase-Inhibitor Complexes When analyzing these structures‚ we observed a reasonably strong hydrogen bond interaction (distance ~ NVL ≫ AAoF ≈ NVoL. Surprisingly‚ the unmodified AAF compound showed a substantially higher level of activity over the unmodified NVL compound. Initially‚ we hypothesized that the modified compounds (No H-Bond) would be less active. To our surprise‚ both modified compounds‚ AAoF and NVoL‚ showed negligible activity (Figure 16). Additionally

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Introduction CL-20 is a energetic compound with high density‚ good oxygen balance (-11%) and high explosive power. However‚ CL-20 has failed to see widespread implementation due to high mechanical sensitivity‚ it is relatively easily detonated by physical forces in comparison to other secondary explosives. While cocrystal CL-20/TNT exhibited a mechanical impact sensitivity greatly reduced relative to that of pure CL-20‚ it was also expected to feature reduced explosive power due to the

Keywords: diethyldithiocarbamate‚ DTA‚ fungicide‚ IR‚ synthesis‚ TG‚ X-ray diffraction Introduction The plant protection has become necessary in order to increase the food production. Many organometallic compounds may have important biological activities. This work is continuation of our previous research on organometallic compounds

Photoelectric Effect: Determining Planck’s Constant Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar January 31‚ 2014 PreLab Up until the eighteenth century‚ particle theories of light dominated physics‚ primarily due to the work of Isaac Newton. Thomas Young’s 1805 famous double-slit experiment‚ which showed that light mimics a wave‚ extinguished some of these early views. However‚ in 1887‚ Heinrich Hertz – who is‚ coincidentally‚ perhaps better known for definitively

Structural colors are created from reflection‚ diffraction and refraction. At times‚ light can reflect away from an object creating many fragments‚ so it is said to be scattering. However‚ if the light changes speed while/before hitting a transparent object‚ it is
