Question

Please refer to Figure 3, which shows the pattern of interference fringes for light of wavelength 675 nm passing through two narrow slits, projected onto a screen a distance of 2.61 m away. The distance on the screen between the centers of two adjacent bright fringes is 1.90 cm. What is the distance between the two slits?

		1.30E-04 m
		5.56E-05 m
		9.27E-05 m

A Helium discharge lamp gives off two wavelengths 611 nm and 485 nm. The diffraction grating has 462 lines/mm that is observered on a screen that is 1.50 m away. What is the distance between the first order fringes of the two different wavelengths? 4.09×10-10 m 2.36 m 1.46 m 0.0965 m
A laser light source with wavelength λ = 545 nm is incident on a diffraction grating (as in the figure). The grating has 495 slits per mm. An observation screen is a distance L = 0.35 m from the grating. What is the separation between individual slits in the grating? Be careful with units: 1 nm = 10-9 m, 1 mm = 10-3 m, and 1 cm = 10-2 m. d = nm What is the distance y along the screen where the first-order diffraction peak is observed? y= cm source grating m=1
