5) An erect object is 50 cm from a concave mirror of radius 60 cm. The character of the image is: 6) Which of the following is a WRONG statement? A) Suggesting that the refractive index of glass decreases with the wavelength of light, we must conclude that in the visible specrtum, the critical angle in glass (for total internal reflection at the interface between glass and air) is smallest for violet light. B) When a bi-chromatic ray of light (with wavelengths of 450 and 650nm) goes from air and obliquely through a glass slab with parallel surfaces, it emerges from the slab as two separate monochormatic rays parallel to the original ray and to each other. C) When light travels from air into water its frequency does not change. D) The value of the Brewster (polarizing) angle for a ray going from air into a transparent material increases as the refractive index of the material increases. E) When you walk away from a flat mirror at a speed v , the distance between you and your image increases at a speed 2 v . 1

### 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.
