Chapter 5: Q64PP (page 1110)

To vary the angle as well as the intensity of polarized light, ordinary unpolarized light is passed through one polarizer with its transmission axis vertical, and then a second polarizer is placed between the first polarizer and the insect. When the light leaving the second polarizer has half the intensity of the original unpolarized light, which statement is true about the two types of cells? (a) Only type H detects this light. (b) Only type V detects this light. (c) Both types detect this light, but type H detects lighter. (d) Both types detect this light, but type V detects more light

Short Answer

Expert verified

Option (d) Both types detect this light, but type V detects more light is the correct option

Step by step solution

01

Polarized light

Polarized light is that which is reflected or transmitted through a certain media so that all the vibrations in the light are restricted to a certain single plane

02

Explanation

Since we are given that the unpolarized light goes through one polarizer with the vertical axis. The light is polarised by this one and then passes through the sound polarizer and reduced to its half intensity. Hence the final polarised light is in the vertical direction, so the type V is the only type that gets detected by the light.

You are in your car driving on a highway at 25m/swhen you glance in the passenger-side mirror (a convex mirror with radius of curvature 150 cm) and notice a truck approaching. If the image of the truck is approaching the vertex of the mirror at a speed of 1.9 m/swhen the truck is 2.0 m/sfrom the mirror, what is the speed of the truck relative to the highway?

In a large vacuum chamber, monochromatic laser light passes through a narrow slit in a thin aluminum plate and forms a diffraction pattern on a screen that is 0.620 m from the slit. When the aluminum plate has a temperature of 20.0掳C, the width of the central maximum in the diffraction pattern is 2.75 mm. What is the change in the width of the central maximum when the temperature of the plate is raised to 520.0掳C? Does the width of the central diffraction maximum increase or decrease when the temperature is increased?

.. DATA At the metal fabrication company where you work, you are asked to measure the diameter Dof a very small circular hole in a thin, vertical metal plate. To do so, you pass coherent monochromatic light with wavelength through the hole and observe the diffraction pattern on a screen that is a distance xfrom the hole. You measure the radius rof the first dark ring in the diffraction pattern (see Fig. 36.26). You make the measurements for four values of x. Your results are given in

the table.

(a) Use each set of measurements to calculate D. Because the measurements contain some error, calculate the average of the four values of Dand take that to be your reported result. (b) For , what are the radii of the second and third dark rings in the diffraction pattern?

A converging lens with a focal length of 12.0 cmforms a virtual image 8.00 mmtall, 17.0 cmto the right of the lens. Determine the position and size of the object. Is the image erect or inverted? Are the object and image on the same side or opposite sides of the lens? Draw a principal-ray diagram for this situation.

Question: Diffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 9.00 cm passes through a slit 12.0 cm wide. A microphone is placed 8.00 m directly in front of the center of the slit. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O. At what distances from O will the intensity detected by the microphone be zero?
