A spherical mirror is to be used to form an image that is 4.75 times the size of the object, on a screen located 5.05.0m behind the object (specifically, the arrangement looks like [image]----- [object] ----- [mirror]).   Part A) What kind of mirror should be used?

An object of 20 cm height and at a distance 70 cm from a plane mirror, what are the image characters and size?  A. Real, inverted, same size B. Virtual, upright, same size C. Vitrual, inverted, same size D. Real, upright, same size

Write P if only statement A is correct, H if only statement B is correct, Y if both statements are correct and S if both statements are incorrect. 1. A. A mirror that curves inward is called a convex mirror. B. Light can be reflected from curved mirrors. 2. A. The focal point of a convex mirror is behind the mirror. B. The image in a concave mirror is always enlarged and upright 3. A. Light is bent when passing through a different medium B. Bending of light is called diffraction 4. A convex lens is a diverging lens. B. Rays of light are bent outwards by a concave lens 5. A. For plane mirrors, the image distance is the same as the object distance. B. Virtual images result when the reflected light diverge.

For the mirror in the attached picture, locate the image by drawing a ray diagram (3 rays) and describe the image. Is it: a. Upright, virtual, reduced. b. Inverted, real, magnified. c. Inverted, virtual, magnified. d. Upright, real, reduced. Thank you.

Multiple Choice: Encircle the letter that corresponds to the correct answer. 1.How do you describe the image formed by a plane mirror? A. The image is virtual, behind the mirror, and enlarged B. The image is virtual, behind the mirror, and of the same size as the object C. The image is real, at the surface of the mirror and enlarged D. The image is real, behind the mirror, and of the same size as the object 2. What is the focal length of a spherical mirror with a radius of curvature of 30 cm is A. 10 cm B. 15 cm C. 20 cm D. 30 cm 3. Where should an object be placed in a concave mirror to form a real image larger than the object? A. at a distance equal to the radius of curvature B. at a distance less than the focal length C. between focus and center of curvature D. at a distance greater than the radius of curvature 4. What is the distance of the image if an object is placed at a large distance in front of a concave mirror of a radius of curvature of 40 cm? B. 30 cm C. 40 cm D. 50 cm A.…
