Physics Honors Quiz: Chapters 23 and 24 1. Lenses that are thicker at the center than at the edges A. cause light rays to diverge. B. bend light rays to a focal point.* C. have no effect on light rays. D. reflect light rays back. E. Not covered in the assigned reading. 2. Light traveling at an angle into a denser medium is refracted A. toward the normal.* B. away from the normal. C. parallel to the normal. D. equally. E. Not covered in the assigned reading. 3. The colors on an oil slick or a soap film are caused by reflection and A. diffraction. B. interference.* C. refraction. D. polarization. E. Not covered in the assigned reading. 4. Diverging spherical mirrors produce images which 5. A light ray, traveling parallel to a converging mirror's axis, strikes the mirror's surface near its midpoint. After reflection, this ray travels A. parallel to the mirror's axis. B. at right angles to the mirror's axis. C. through the mirror's center of curvature. D. through the mirror's focal point.* E. Not covered in the assigned reading. 6. A coverging lens has focal length f . An object is placed a distance of 1.5 f from the lens. The image formed is __________ and ___________ the object. 7. Monochromatic light from a distant source is incident on two parallel narrow slits. After passing through the slits the light strikes a screen. What will be the nature of the pattern of light observed on the screen? A. The screen will be most brightly lit at its center, with the intensity decreasing slowly and uniformly on either side. B. A series of alternating light and dark bands.* C. A rainbow of colored lines will be seen spreading out on either side of the center. D. Two bright bands of light, one in line with each slit. E. The screen will be uniformly illuminated except for two dark bands, one in line with each slit.

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.
