An object is placed in front of two thin coaxial lenses 1(convex) and 2 (concave). The focal points for lens 1(convex) and 3cm from the lens: those for lens 2 (concave)are 6cm from the lens. The lenses have separation L=8.5 cm, and the pencil is 9 cm to the left of lens 1. a) Where does the system of two lenses produce an image of the object? b) The object has height h=2mm. What is the height of image 2?...

Chapter 34, Problem 062 Lenses with given radii. Object O stands in front of a thin lens, on the central axis. For this situation, each problem in the table (below) gives object distance p, index of refraction n of the lens, radius r 1 of the nearer lens surface, and radius r2 of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also,...

10. Two lenses are in contact. One of the lenses has a focal length of +10.0cm when used ale When the two are in combination, an object 20.0cm away from the lenses forms a reali 40.0cm away from the lenses. What is the focal length of the second lens? Show your w 9. One lens has a focal length of +15.0 cm. A second lens of focal length +20.0cm is placed in contact with the first lens. What is the...

PROBLEM #2: Max has two pairs of polarized sunglasses. Each of the four lenses has a polarization axis that is vertical (perpendicular to the ground) when worn. Max removes three of the lenses from the glasses and arranges them in front of the fourth lens so that the polarization axes of the first and the fourth lens are perpendicular to each other. He places the other two lenses between the outermost lenses, rotating the second and third lens so that...
