Lab equipment will be used to measure force, mass, and acceleration. Force data will be measured by a wireless force sensor which must be calibrated. Position data will be measured by a CBR sonic ranging device.
The following items should be in the Light and Color portion of your notebook. They should be clearly organized and easy to find. Use an organizational system and label all work.
Each lab will be graded separately. Ripple Tank Lab Question: How is the path difference related to the wavelength of light for a two-point source interference pattern? To develop two equations one for nodes and one for anti-nodes for relating the path difference to the wavelength for a two-point source interference pattern.
The Data Section should include the provided pattern with marked nodal and antinodal lines, marked nodes and antinodes, Atwood motion lab a table of data listing S1P, S2P and PD distances expressed in terms of wavelengths.
The Conclusion should state two equations relating path difference to wavelength - one for nodal positions and the other for antinodal positions. The symbols used in the equation should be defined. The Discussion of Results section should describe the evidence which leads to the conclusion statement; specific trials of data should be referenced in order to demonstrate the evidence leading to the equation.
What are the limitations of the two methods of calculating the wavelength of light from an interference pattern?
To analyze a two-point source interference pattern using both the path difference equation and Young's equation and to compare the effectiveness of each equation in determining the wavelength. The Data section should include the provided diagram and data table; work should be clearly shown and labeled for the couple of calculations which are performed.
Comments should be made about which method equation is most effective; the evidence for your comments should be discussed. Young's Experiment Lab What is the wavelength of red laser light? To determine the wavelength of red laser light in units of nanometers. The Data section should include a top view of the experimental set-up with measured values labeled on the diagram; the measurements should be related to the variables y, d, m, and L and the units should be clearly stated.
Calculations should be clearly and systematically shown; conversion of units should be part of the work; units should be stated. The Conclusion should state the experimentally-determined value for the wavelength of red light.
The Discussion of Results section should include an error analysis; a percent error calculation should be included in the discussion; work should be shown. What model of light and of Polaroid filters would provide a suitable explanation of how they work? To explore Polaroid filters and to develop and describe a model which explains how they work.
The Data section should include a documented record of the tests which were performed with the filters and the corresponding observations and results. The record should be clear and accentuated by diagrams and sketches. The discussion should be supported by specific references to evidence which was documented in the Data section.
Diluted by Distance Lab Question:Rotational Kinematics: Using an Atwood's Machine Introduction The purpose of this lab is to help you understand angular velocity and angular acceleration.
Shop Industrial Handles & Pulls on timberdesignmag.com Handles and pulls are available in many different material types, styles, and sizes.

Execution Watch with Ray Hill can be heard on KPFT FM, in Galveston at , Livingston at , and in Huntsville at as well as on the net here from PM CT to PM CT.
Atwood's Machine Frictionless case, neglecting pulley mass. Application of Newton's second law to masses suspended over a pulley: Atwood's machine. For hanging masses: m 1 = kg m 2 = kg the weights are m 1 g = N m 2 g = N The acceleration is.
Polymerase chain reaction (PCR) is a method widely used in molecular biology to make multiple copies of a specific DNA segment. Using PCR, a single copy (or more) of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of the particular DNA segment.
PCR is now a common and often indispensable technique used in medical laboratory and clinical laboratory. Caravan and RV parts and accessories.
