A convex mirror has a Radius of Curvature of 5.80 cm and is the second optical device (spherical mirror or thin lens) in an optical system. The image from the first optical device becomes an object for the second device. For the given convex mirror, a virtual image is located 39.7 cm away on the optical axis. Answer the following questions. All answer tolerance ±5 on the third significant digit. a) Calculate the mirror's focal length. Number b) Calculate the object distance. Number c) Is the object real or virtual? Real Virtual Units O Upright Units d) Calculate the maginification of the mirror. Number e) Relative to the image, is the object inverted or upright? Inverted

You have a concave spherical mirror (the same holds if you had a convex mirror) If the value of q (the distance from the image to the mirror along the principal axis of the mirror) is 0.68m and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 3.37m, what is the focal length of the mirror? h B Al C h' The magnification equation and the sign convention for q imply that real images of real objects are always inverted (if both p and q are positive, m is negative); virtual images of real objects are always upright (if p is positive and q is negative, m is positive). Keeping the signs of p and q straight in your mind is the most challenging aspect of mirrors (and lenses). Fortunately, table 23.2 summarizes when p and q are positive and when they are negative.

A concave spherical mirror has a radius of curvature of 20 cm. Give your answers with units. a) What is the image distance for an object at a distance of 30 cm from the mirror? Number Units b) Is this image real or virtual? O real O virtual c) What is the image distance for an object at a distance of 5 cm from the mirror? Number Units d) Is this image real or virtual? real O virtual

Question 6 of 15 A 3 cm tall object is placed in front of a concave mirror. The magnitude of the mirror's focal length is 4 cm. An image is formed on the back side of (behind) the mirror and is located a distance of 2 cm from the mirror. What is the object distance and the image height? 1.33 cm, 4.50 cm 4.00 cm, 1.50 cm 2.00 cm, 1.50 cm 1.33 cm, 1.50 cm 4.00 cm, 4.50 cm
