1.) A double-concave lens focal length -20 cm has an object placed at a distance of 30 cm in front of it. How far from the mirror is the image formed? On what side of the lens is the image formed? What is the magnification? Is the image real or virtual? Upright or inverted?
2.) The second order fringe is located 5-cm from the central fringe when formed by a 10 lines/mm diffraction grating on a screen 5 meters away. What is the wavelength of light being used?
3.) A three-layer parallel-boundary system consisting of air, then water (index of refraction 1.33), then glass (index of refraction 1.5) has light passing through it. The beam of light begins in the glass, refracting through the glass/water boundary, then undergoes total internal reflection at the water/air boundary. What must the angle of incidence be at the glass/water boundary?

An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...
