LEARN MORE REMARKS This calculation depends on the angle @ being small because the small angle approximation was implicitly used. The measurement of the position of the bright fringes yields the wavelength of light, which in turn is a signature of atomic processes, as is discussed in the chapters on modern physics. This kind of measurement therefore helped open the world of the atom. QUESTION Which of the following make the separation between fringes greater in the two slit interference experiment? (Select all that apply.) O Larger separation of the two slits. O Narrower slits. O wider slits. O Smaller separation of the two slits. PRACTICE IT Use the worked example above to help you solve this problem. A screen is separated from a double-slit source by 1.12 m. The distance between the two slits is 0.0302 mm. The second-order bright fringe (m = 2) is measured to be 4.55 cm from the centerline. (a) Determine the wavelength of the light. nm (b) Determine the distance between adjacent bright fringes. cm EXERCISE HINTS: GETTING STARTED I 'M STUCKI Suppose the same experiment is run with a different light source. If the first-order maximum is found at 1.90 cm from the centerline, what is the wavelength of the light? nm Need Help? Read It
