Problem 1. A concave-convex lens with index of refraction n = 3/2, radii of curvature R1 = ?3cm and R2 = 1cm is 4cm to the left of a diverging lens having focal length ?2cm. An object is placed to the left of both lenses at a distance 7 cm from the concave-convex lens. (a) Where is the final image formed by this combination of lenses? (b) Is the final image upright or inverted? (c) Is the final image real...

7. An object is placed at a distance of 80 cm left of a converging lens with a focal length of 30 cm. . Calculate the image distance. Is the image virtual or real? If the object is 8 cm tall, what is the size of the image? A diverging lens with the same focal length is placed 10 cm right of the first lens. Determine final image position and magnification. 8. A light ray strikes a flat piece of...

5. What was the focal distance (f) when the radius of curvature was 0.8 and index of refraction was 1.6? 6. Calculate the radius of curvature of a lens with a focal distance of 40.0 cm and an index of 1.2. 7. An object placed 3cm away from a lens projects a real image 0.6m behind the lens. What is this lens focal distance? 8. What is the lens magnification? 9. An object 20.0 cm to the left of a...

A convex lens is a transparent instrument that uses refraction to bend and focus light from an object, forming a sharp image. We'll first investigate how the lens produces an image from a point source of light (a lamp). Select Screen at upper right, which makes the object a lamp and gives a black screen that can be dragged around. Select Many rays at upper left to see how the lens bends some of the rays of light from the...

6. A 4.00-cm tall light bulb is placed a distance of 45.7 cm from a double convex lens having a focal length of 15.2 cm. Determine the image distance and the image size. 7. A 4.00-cm tall light bulb is placed a distance of 8.30 cm from a double convex lens having a focal length of 15.2 cm. (NOTE: this is the same object and the same lens as in #6, only this time the object is placed closer to...
