Homework 1 (due: January 27) 1. How long does it take light to travel 10 m in glass? The index of refraction of glass is 1.6. 2. A traveling wave is described by the following equation E(x,t) = 5 sin(4.4 x + 10 t). Find (a) period, (b) wavelength, and (c) speed of this wave. 3. A 0.5-mm-wide spit is illuminated by light of wavelength 500 nm. What is the width of the central maximum on a screen 2.0 meter behind the slit? 4. A diffraction grating having 800 lines/mm diffracts light at 40 0 . What is the light wavelength? 5. A double-slit experiment is performed with light of wavelength 600 nm. The bright interference fringes are spaced by 1.8 mm apart on the viewing screen. What will the fringe spacing be if the light is changed to a wavelength of 400 nm? 6. A double-slit interference pattern is created by two narrow slits spaced 0.2 mm apart. The distance between the first and the fifth minimum on a screen 60 mm behind the slits

What is the width of a slit for which the first minimum is at 45 when the slit is illuminated by a helium-neon laser (wavelength = 633 nm)? 8. A diffraction grating produces a first-order maximum at an angle of 10 . What is the angle of the second-order maximum? 9. A double-slit experiment is performed with light of wavelength 500 nm. The bright interference fringes are spaced by 6 mm apart on the viewing screen. . What will the fringe spacing be if the whole system is placed in a medium with index of refraction of 2.5? 10. A laser beam with wavelength 500 nm is incident on two slits 0.5 mm apart. The interference pattern is observed on a screen 1 m away from the plane of the slits. Determine the number of maxima on the screen within an interval -5.5 mm<y<5.5 mm. Point y=0 corresponds to the center of the pattern....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
