Optics Problem Sheet
Find the distance between the left and right 1st dark spots if light of wavelength 500 nm is incident on a single slit of width .35 mm located 2.0 m form a screen.
White light is incident on a diffraction grating. In the fourth order, the red end (700 nm) is located at an angle of 40°. a) Find the number of lines per cm of the diffraction grating. b) Find the angle made by the corresponding blue end (350 nm).
Light of wavelength 633 nm is incident on a single slit of width .05 mm. The diffraction pattern is projected on a screen located a distance of 1.0 m away. a) Sketch the pattern projected on the screen. b) How would the projected pattern change if the screen were moved further away? c) Find the distance from the central spot to the first dark spot on the screen.
