Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

Famous Thinkers PHL458 2/17/2014 Tiffany Faison Famous Thinkers When thinking of famous thinkers‚ people who reached deep into the far spaces of their minds‚ who used such creativity to imagine a world that seems so science fiction at their present time and then to find a way to make that dream‚ a reality. The two men who come to mind the most would be Bill Gates and Dr. Martin Luther King Jr. These two men used their minds to think of a way to forge a path of innovation‚ Bill Gates revolutionized

Mariah Mitchell was born in 1818. Mitchell grew up in Nantucket Massachusetts‚ she was the third oldest of ten children. Her father was the one who helped her with her interest in astronomy. At an early age Maria’s father “used stellar observations to check the accuracy of chronometers for Nantucket‚ Massachusetts‚ whalers and taught his children to use a sextant and reflecting telescope” (Sarah Zielinski‚ smithsonian.com). Maria got a good education at a “school at which her father was the master”

Flame Test Lab - Post Lab Questions and Pre-Lab Questions Pre-Lab Questions: 1.When an atom absorbs energy‚ the electrons move from their normal state to an excited state. When an atom emits energy‚ the electrons move from an excited state to their ground state and give off photons. 2.Is the flame test a qunatitative test or qualitative test for the identity of an unknown? This flame test is both quantitative and qualitative. It is quantitative because we are measuring the wavelength

Implementation of a Chirped Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer Abstract: Under the condition in which electric and magnetic fields are absent‚ rotational constants is a three molecular constants that substantiate polyatomic molecule. In this laboratory experiment at Missouri University of Science and Technology‚ we are going to collect rotational spectra by using 2 separate types of microwave spectrometers -- the FTMW (Fourier Transform Microwave) spectrometer and CP-FTMW
