PHY2061 R. D. Field Problems Chapter 42 Page 1 of 1 Chapter 42 Problems Problem 1: If monochromatic light of wavelength 500 nm is incident on a single narrow slit 0.02 mm wide, what is the width of the central bright spot ( in cm ) on a screen that is 3 meters from the slit? (Hint: the width of the central bright spot is equal to the distance between the two first order minima.) Problem 2: Monochromatic light of wavelength 600 nm is incident on a single narrow slit and produces a diffraction pattern on a screen 2 meters away? If the screen is moved 1 meter

Unformatted text preview: further away from the slit, what wavelength of monochromatic light ( in nm ) will produce a diffraction pattern with all the diffraction minima at the same points on the screen? Problem 3: Blue light ( = 470 nm ) falls on a wall with a single slit of width 0.18 mm and produces a diffraction pattern on a screen located a distance L from the slit. If the color of light is changed to red ( = 650 nm ), the width of the central bright spot on the screen increases by 1.0 cm . What is the distance L to the screen ( in meters )?...
