The distance between the lens and the mirror is 1.0 cm. Ycm abect morror leas a) What is the radius of curvature of the mirror? b) Is the mirror concave or convex? c) There are a sequence of images produced as light passes through the lens, reflects off of the mirror and goes back through the lens. Where is the final image? d) What is the magnification of the final image? e) Is the final image real or virtual? Is it upright or inverted? (Hint: The distances are all integer numbers of cm. This should tell you if you make a mistake.A glass (n=1.5) biconvex lens has radii of curvature of +15 cm and -18 cm. If an object is placed at 10 cm left of the left surface of the lens, what is the image distance? Calculate the magnification and orientation of the image.The image is formed on the retina even when the distance of the object from the eye increases The lens of the eye becomes thinner and the focal length increases. O The lens of the eye becomes thicker and the focal length decreases. The lens of the eye becomes thinner, and the focal length decreases. с The lens of the eye is not affected and remains the same thickness. O
