You set up an experiment with two polarizer screens on an optical bench and collect data for the intensity of the light at the detector as you vary the relative angle between the transmission axes of the polarizers. You create a plot of light intensity (in lux) vs cos2 θ with your data and get a linear fit for your graph gives a slope of 120.2 ± 1.204 and a y-intercept of 15.45 ± 2.141.
(a) What is intensity of the light source you used in your experiment?
(Answer ± Answer) lux

You have two polarizers on an optical rail between an unpolarized light source (of intensity I0) and a detector. Polarizer 1 is oriented at an angle of θ1 = 40° from the horizontal, and polarizer 2 is oriented horizontally (θ2 = 0°). (a) What is the intensity of the light after it passes through only polarizer 1? Express your answer as a fraction or decimal in terms of I0 (i.e. I = 1⁄4 I0). (b) What is the intensity of...

The sensor has is capable of a maximum measurement of about 600-700 lux. To be sure this doesnt introduce φ problems in the data collection you will need to find the position where the sensor reads a maximum value. To do this, place the light and the sensor on the optical bench and slide the sensor toward the light while watching the reading on the screen. Find the position where the reading no longer increases. This will be the shorter...

question 7 and 8
Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...

Suppose you are planning to collect a set of data in an experiment where the null hypothesis states that the population mean will be 15. You plan to collect 30 observations, and you expect the population standard deviation to be 6.5. Use the Statistical Applet: P-value of a Test of Significance to calculate the P-value for your final test of significance, considering the possibilities that your sample mean comes out to 12, 13, or 14, and considering the two possible...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
