CP In a laboratory, light from a particular spectrum line of helium passes through a diffraction grating and the second-order maximum is at 18.9° from the center of the central bright fringe. The same grating is then used for light from a distant galaxy that is moving away from the earth with a speed of 2.65 × 107 m/s. For the light from the galaxy, what is the angular location of the second-order maximum for the same spectral line as was observed in the lab? (See Section 16.8.)

- A circular diaphragm 62.72 cm in diameter oscillates at a frequency of 15.97 kHz as an underwater source of sound used for submarine detection. Far from the source, the sound intensity is distributed as the diffraction pattern of a circular hole whose diameter equals that of the diaphragm. Take the speed of sound in water to be 1450. m/s, and find the angle (in degrees) between the normal to the diaphragm and a line from the diaphragm to the first minimum.arrow_forwardU:04) Coherent light with wavelength 670 nm passes through two narrow slits and the interference pattern is observed on a screen 40.0 cm from the slits. The distance from the m = 1 bright fringe (above the central maximum) to the m = −1 bright fringe (below the central maximum) is 22.00 cm. What is the distance on the screen from the m = 2 bright fringe to the m = −2 bright fringe?arrow_forwardTwo observers stand 20 m apart on a line that connects them and a spherical light source. If the observer nearer the source measures a light intensity 59 %% greater than the other observer, how far is the nearer observer from the source?arrow_forward
- How can I calculate the phase difference, in radians, between the rays from the two slits as they strike the screen at the specified distance from the central maximum, given an electromagnetic radiation of intensity I0 = 340 W/m2 that passes through two parallel narrow slits that are d = 1.4 μm apart and strikes a screen located L = 2.2 m from the slits. The intensity of the radiation on the screen at y = 3.9 mm from the central interference maximum is I = 95 W/m2. I know the equation is 2 acos (I/I0)1/2 but can't figure out the answer.arrow_forwardIn a large vacuum chamber, monochromatic laserlight passes through a narrow slit in a thin aluminum plate and formsa diffraction pattern on a screen that is 0.500m from the slit. When thealuminum plate has a temperature of 20.0C, the width of the centralmaximum in the diffraction pattern is 2.75 mm. What is the change inthe width of the central maximum when the temperature of the plate israised to 520.0C? Does the width of the central diffraction maximumincrease or decrease when the temperature is increased?arrow_forwardCoherent light from a laser diode is emitted througha rectangular area 3.0 μ m x 1.5 μ m(horizontal-byvertical).

When illuminated by white light and viewed directly (perpendicular to the surface), what wavelength in the visible spectrum (375nm to 725nm) will be strongly reflected?arrow_forwardAn investigator finds a fiber at a crime scene that he wishes to use as evidence against a suspect. He gives the fiber to a technician to test the properties of the fiber. To measure the diameter of the fiber, the technician places it between two flat glass plates at their ends as in Figure P24.24. When the plates, of length 14.0 cm, are illuminated from above with light of wavelength 6.50 x 102 nm, she observes bright interference bands separated by 0.580 mm. What is the diameter of the fiber?arrow_forwardMourning doves have a small batch of iridescent feathers.
