Two lenses are placed a distance of 20.0 cm apart. The leftmost lens is a converging lens with a focal length of 11 cm while the seconds lens is a diverging lends with a focal length of 6 . If an object is placed 2 cm to the left of the converging lens, determine the magnification of the two lenses combined.
4. Analysis of an interference effect in a clear solid shows that the wavelength of light in the solid is 428.9 nm. Knowing this light comes from a He-Ne laser and has a wavelength of 633 nm in air, determine the index of refraction of the material.
