Lesson: Single-Slit Diffraction High School Physics

Light of wavelength 475 nm passes through a slit 8.25 μm in width and falls onto a screen 4.6 cm in front of the slit, producing a diffraction pattern that has its central maximum at a point directly in front of the slit. The angle that light in the diffraction pattern makes with the line passing through the center of the slit and the center of the diffraction pattern is small enough for . What is the width of the central maximum of the pattern? Answer to two significant figures.

Light of wavelength 550 nm passes through a slit 7.55 μm in width and falls onto a screen 12.5 cm in front of the slit, producing a diffraction pattern that has its central maximum at a point directly in front of the slit. The angle that light in the diffraction pattern makes with the line passing through the center of the slit and the center of the diffraction pattern is small enough for . What is the distance from the central maximum of the diffraction pattern to the first minimum of the pattern?

Light of wavelength passing through a narrow slit of width falls on a screen where a diffraction pattern is produced. Which of the following formulas correctly relates and to the angle from a line that intersects the center of the slit and the center of the diffraction pattern to a line that intersects the center of the slit and a minimum of the diffraction pattern of order ?
