Two polaroid sheets are inserted between two other polaroid sheets which have their transmission directions crossed so that the angle between each successive pair of sheets is 30 degrees. Find the transmitted intensity if the original light is unpolarized with intensity Io=40.0 W/m^2 a.15 b. 20 c. 8.44 d. 6.33 e. 11.3
Unpolarized light is passed through three successive Polaroid filters, each with its transmission axis at 45.0° to the preceding filter. Present the graph describing difference in percentage of light transmitted through the second and third filters with dependence on the angle between their transmission axises. Draw this graph. Analyze information presented on the graph. Make a decision about at what angle between the second and third filter the highest difference in percentage of transmitted light can be observed. Explain.
Unpolarized light is incident on a series of two Polaroid sheets. The intensity of the light emerging from the second sheet is 9.30% of the intensity of the light incident on the first sheet. Find the angle between the transmission axes of the two sheets.
Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer makes an angle of 34.1° with the axis of the polarizer. (a) What fraction of the original unpolarized light is transmitted through the analyzer? (b) What fraction of the original light is absorbed by the analyzer?
Two polarizing sheets are placed together with their transmission axes at an angle of 68.0° to each other. A third sheet is inserted between them with its transmission axis at an angle of 34.0° with respect to each of the other axes. Find the fraction of incident unpolarized light intensity transmitted by the three-sheet combination. (Assume each polarizing sheet is ideal.)
Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer makes an angle of 40.0° with the axis of the polarizer. (b) What fraction of the original light is absorbed by the analyzer (the second polarizer)? (that is find (I adsorbed/ I incident on the first polarizer))
You look through a Polaroid sheet at a 150 W light bulb 3.21 m away. (a) Find the intensity of the light you see (b) Next you place a second Polaroid sheet in front of the first sheet with an angle of 49.3° between the two transmission axes. What intensity do you observe?
You look through a Polaroid sheet at a 100 W light bulb 2.97 m away. (a) Find the intensity of the light you see. (b) Next you place a second Polaroid sheet in front of the first sheet with an angle of 44.1° between the two transmission axes. What intensity do you observe?
You look through a Polaroid sheet at a 100 W light bulb 2.70 m away. (a) Find the intensity of the light you see. (b) Next you place a second Polaroid sheet in front of the first sheet with an angle of 49.3° between the two transmission axes. What intensity do you observe?
You look through a Polaroid sheet at a 150 W light bulb 2.85 m away. (a) Find the intensity of the light you see. (b) Next you place a second Polaroid sheet in front of the first sheet with an angle of 45.7° between the two transmission axes. What intensity do you observe?
