Serway CP 24 04 001 10.0 points Light of wavelength 497 nm falls on two slits spaced 0 . 335 mm apart. What is the required distance from the slit to a screen if the spacing between the first and second dark fringes is to be 3 . 32 mm? Correct answer: 2 . 23783 m. Serway CP 24 09 002 10.0 points Waves from a radio station have a wavelength of 329 m. They travel by two paths to a home receiver 18 . 3 km from the transmitters. One path is a direct path, and the second is by reflection from a mountain directly behind the home receiver. What is the minimum distance from the mountain to the receiver that produces de- structive interference at the receiver? (As- sume that no phase change occurs on reflec- tion from the mountain.)

What students are saying

• 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.
