Two slits separated by 2.00 × 10^-⁵m are illuminated by light of wavelength 625 nm. If the screen is 6.00 m from the slits, what is the distance between the m = 0 and m = 1 bright fringes? A)18.8 cm B)12.5 cm C)15.6 cm D)20.3 cm E)21.4 cm

Question

Quizplus · Accepted Answer

The distance between the m = 0 and m = 1 bright fringes is given by:$$d = \frac{\lambda D}{d}$$where:d is the distance between the slitsλ is the wavelength of lightD is the distance between the slits and the screenPlugging in the given values, we get:$$d = \frac{(625 	imes 10^{-9} 	ext{ m})(6.00 	ext{ m})}{2.00 	imes 10^{-5} 	ext{ m}} = 18.8 	ext{ cm}$$
