if the assumed angles are not as in the question please make sure that angles are what.
In the questions that follow, assume that all angles are measured counterclockwise from the +x axis in the direction of the +y axis. Part A A beam of polarized light with intensity I0 and polarization angle θ0 strikes a polarizer with transmission axis θTA. What angle θ should be used in Malus's law to calculate the transmitted intensity I1? This process is illustrated in the figure (Figure 2) , where the polarization of the light wave is visually illustrated by...
Intensity level is given by b = 10 log(I/I0) with I0 = 10−12 W/m2. The usual threshold of human hearing is defined as intensity level of b = 0 dB. What does this actually mean in terms of sound intensity?
In Experiment 1, unpolarized light of intensity 100 W/m2 is sent through a polarizer A and is then incident on a polarizer B with axis perpendicular to that of Polarizer A. In Experiment 2, a third polarizer C is placed between A and B such that the polarization axis of C is 45 degrees from that of A and B. Which of the following is true? a. The intensity of light transmitted through B will be 0W/m2 in Experiment 1...
8. A polarized light that has an intensity I0 = 62.0 W/m² is incident on three polarizing disks whose planes are parallel and centered on a common axis. Suppose that the transmission axis of the first polarizer is rotated 14° relative to the axis of polarization of the incident light, and that the transmission axis of each additional analyzer is rotated 14° relative to the transmission axis of the previous one. Calculate the transmitted intensity through all polarizers. _________ W/m2
Unpolarized light of intensity 100 W/m2 is incident on polarizer #1. After passing through polarizer #1, the light then passes through polarizer #2 whose transmission axis is at 20 degrees to that of polarizer #1. What is the intensity of the light transmitted through polarizer #2? (in units of W/m2)
Unpolarized light of intensity 60 W/m2 is incident on polarizer #1. After passing through polarizer #1, the light then passes through polarizer #2 whose transmission axis is at 50 degrees to that of polarizer #1. What is the intensity of the light transmitted through polarizer #2? (in units of W/m2)
Unpolarized light passes through two polarizers whose transmission axes are at an angle of 25.0 ∘ with respect to each other. What fraction of the incident intensity is transmitted through the polarizers? I/I0 equals:
1. The intensity of a particular earthquake wave is measured to be 1.60 x 106 W/m2 at a distance of 40.0 km from the source. What was the intensity when it passed a point only 1.00 km from the source? Assume that earthquake waves travel uniformly in all directions W/m2 2. The team monitoring a space probe exploring the outer solar system finds that radio transmissions from the probe take 2.10 hours to reach earth. How distant (in meters) is...
Using an intensity of 1 × 10-12 W/m2 as a reference, the threshold of hearing for an average young person is 0 dB. Person 1 and person 2, who are not average, have thresholds of hearing that are β1 = -11.0 dB and β2 = +9.00 dB. What is the ratio I1/I2 of the sound intensity I1 when person 1 hears the sound at his own threshold of hearing compared to the sound intensity I2 when person 2 hears the...
4) a) An unpolarized beam of light with intensity 1000 W/m2 is incident on polarizer P, an ideal linear polarizer with transmission axis along the x-axis. The transmitted light is then incident on a second ideal inear polarizer P2, which has transmission axis oriented 50 with respect to Pi. What is the intensity of the light transmitted through P2? b) Now another ideal linear polarizer Ps is inserted between Pi and P2. Its transmission axis is rotated halfway between that...
