Absorption & Emission of Light Stimulated Absorption & Emission‚ Spontaneous Emission E2 Incident radiation hν hν Emitted & transmitted radiation E1 Resonance condition E2-E1=hν • Rate of stimulated emission is: −dN1/dt = N1B1->2 ρ(ν) • Rate of absorption is the sum of the rated due to stimulated emission and spontaneous emission: −dN2/dt = N2B2->1 ρ(ν) + N2A2->1 where B1->2 is the Einstein transition probability for induced absorption‚ B2->1 is the Einstein transition probability

So I sat back‚ riding my way through junior year while continuing to audition and help the theatre

Abstract The primary purpose of this laboratory experiment was to record the effects that light exercise has on different cardiovascular functions such as mean blood pressure‚ cardiac out put‚ and total peripheral resistance by comparing both of the numerical values before and after exercise. Prior to exercise‚ the mean blood pressure (MBP) was 86.8 mmHg with a standard deviation of 7.4. After exercise‚ MBP was 96.3 mmHg with a standard deviation of 9.2. The cardiac output (CO) was 5.3 Liters/minute

September 9‚ 2013 Learning parts and proper use of microscope‚ and the interception of images viewed through a light microscope Abstract: A compound light microscope uses two sets of lenses‚ ocular and objective‚ and employs light as its source of illumination. Through careful observation‚ we identified the various parts of a light microscope we found that the light microscope Ocular lenses which give 10x magnification power‚ and objective lenses which consist of three objectives: scanning

The book "Friday Night Lights"‚ is a book about a team of high school football players; all with different characters‚ personalities‚ and situations. The town of Odessa‚ in Texas is where the story begins and takes place in. To some of the players‚ football is just a game and for others‚ it is much more. To portray the mood and feeling that there is more than what meets the eye‚ Bissinger uses various rhetorical strategies throughout writing the book; however the strategies that are more often seen

Automatic Street Light Control System is a simple and powerful concept‚ which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes.
