In procedure 2: suppose a beam of monochromatic (single frequency)light, wavelenth 478 nm falls on a double slit whose slits are0.0307 mm apart. The screen is 70.3 cm from the slits.
a) Calculate the distance from the central maximum to the firstmaximum.
cm
b) Calculate the distance from the central maximum to the tenthminimum.
cm
3. â/2 points Notes
Suppose procedure 2 is done with a diffraction grating with 487,000lines per centimeter.
a) Find d, the distance between the lines.
cm
b) Light hits this diffraction grating, and goes onto a screendistance 84.1 cm away, creating a diffraction pattern where themaxima are 21.9 mm apart. Find the wavelength of the light beingused. NOTE: the light may not be visible!
