A) At what angle will 642 nm light produce a first-order maximum when falling on a grating whose slits are 1.8 × 10-3 cm apart? B)At what angle will 513 nm light produce a second-order maximum when falling on a grating whose slits are 1.19 × 10-3 cm apart? C) A grating that has 3,904 slits per cm produces a third-order fringe at a 21.7° angle. What wavelength of light is being used in nm?
Monochromatic light passing through a two slits which are 3.6 µm apart produces a second-order fringe at an angle 18.0°. (a) What wavelength of light is being used? (b) Draw a diagram indicating the 1st and 2nd order fringes. (c) If the screen is 0.75-m away, how far (in cm) is the 2nd order bright fringe from the center?
A)How many slits per centimeter does a grating have if the third order occurs at a 17° angle for 629 nm light? B) What is the highest spectral order that can be seen if a grating with 6500 slits per cm is illuminated with 633 nm laser light? Assume normal incidence (θ = 90 o). Hint: round down and write it as an integer.

Monochromatic light falling on two slits 1.4×10−2 mmapart produces the fifth-order fringe at an 8.4 ∘ angle. What is the wavelength of the light used?
For a wavelength of 490 nm, a diffraction grating produces a bright fringe at an angle of 26°. For an unknown wavelength, the same grating produces a bright fringe at an angle of 36°. In both cases the bright fringes are of the same order m. What is the unknown wavelength? Bright fringe m (unknown wavelength) Bright fringe m (known wavelength) Central bright fringe (m- 0) Bright fringe m (known wavelength) Bright fringe m (unknown wavelength) Diffraction grating Screen
