Answer #1

To determine the image distance, the lens equation can be used two times. Apply lens equation to first lens and obtain the image distance d. Simultaneously find the magnification m1.Now this image of first lens will act as the object for the another lens. Now apply the lens equation for the second time and obtain the image distance.Obtain the magnification m2.

To obtain the net magnification , multiply both magnification produced due to first and the second lens.

mnet=m1.m2

You have a concave (diverging) lens with a −31 cm focal length. The magnification produced by the lens for a particular object distance is m = 1/2 and you wish to decrease the magnification to m = 1/5. Determine the distance and direction (away from or closer to the lens) through which the object must be moved in order to accomplish this.

Consider a two-lens system consisting of a diverging lens (f=-27.0 cm) and a converging lens (f=22.0 cm). An object is placed 7.0 cm to the left of the converging lens and a final image is produced by the two-lens system that is 20.0 cm to the left of the diverging lens. If the converging lens is to the left of the diverging lens, how far apart are the two lenses?

Use the thin lens equation and the equation for magnification, to show that for a single diverging lens that the image of a real object is always virtual, upright, and reduced. (Hint: Solve the lens equation for di and substitute into the equation for magnification. Discuss the value and sign of magnification for negative values of f.

An achromat is a two-lens system in which the chromatic aberration of a biconvex positive lens is corrected by a plano-concave negative lens. The light passes through the positive lens before the negative lens. Both lenses have different indexes of refraction. A successful achromat will make the image produced by the two-lens system form at the same point for both blue light at 450 nm and red light at 650 nm. 1. How far from both lenses is the image...

Which is true about a system of two lenses with a common central axis? The overall lateral magnification is the product of the individual lateral magnifications. The overall lateral magnification is the ratio of the first lateral magnification to the second lateral magnification. The overall lateral magnification is the sum of the individual lateral magnifications. Which is true of the angular magnification of a simple magnifying lens?
