Q: A lens made of glass (ng = 1.52)
A lens made of glass (ng = 1.52) is coated with a thin film of MgF2 (ns = 1.38) of thickness t. Visible light is incident normally on the coated lens as in Figure P24.30. (a) For what minimum value of...
See AnswerQ: Light of wavelength 5.40 x 102 nm passes through a
Light of wavelength 5.40 x 102 nm passes through a slit of width 0.200 mm. (a) Find the width of the central maximum on a screen located 1.50 m from the slit. (b) Determine the width of the first - or...
See AnswerQ: A student and his lab partner create a single slit by carefully
A student and his lab partner create a single slit by carefully aligning two razor blades to a separation of 0.500 mm. When a helium–neon laser at 633 nm illuminates the slit, a diffraction pattern is...
See AnswerQ: Light of wavelength 587.5 nm illuminates a slit of width
Light of wavelength 587.5 nm illuminates a slit of width 0.75 mm. (a) At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 0.85 mm from the...
See AnswerQ: Microwaves of wavelength 5.00 cm enter a long, narrow
Microwaves of wavelength 5.00 cm enter a long, narrow window in a building that is otherwise essentially opaque to the incoming waves. If the window is 36.0 cm wide, what is the distance from the cent...
See AnswerQ: A beam of monochromatic light is diffracted by a slit of width
A beam of monochromatic light is diffracted by a slit of width 0.600 mm. The diffraction pattern forms on a wall 1.30 m beyond the slit. The width of the central maximum is 2.00 mm. Calculate the wave...
See AnswerQ: A screen is placed 50.0 cm from a single slit
A screen is placed 50.0 cm from a single slit that is illuminated with light of wavelength 6.80 x 102 nm. If the distance between the first and third minima in the diffraction pattern is 3.00 mm, what...
See AnswerQ: A slit of width 0.50 mm is illuminated with light
A slit of width 0.50 mm is illuminated with light of wavelength 5.00 x 102 nm, and a screen is placed 1.20 x 102 cm in front of the slit. Find the widths of the first and second maxima on each side of...
See AnswerQ: The second - order dark fringe in a single - slit diffraction
The second - order dark fringe in a single - slit diffraction pattern is 1.40 mm from the center of the central maximum. Assuming the screen is 85.0 cm from a slit of width 0.800 mm and assuming monoc...
See AnswerQ: Three discrete spectral lines occur at angles of 10.1°,
Three discrete spectral lines occur at angles of 10.1°, 13.7°, and 14.8°, respectively, in the first - order spectrum of a diffraction - grating spectrometer. (a) If the grating has 3660 slits/cm, wha...
