A spherical, concave shaving mirror has a radius of curvature of 0.609 m. What is the image distance of a person's face when it is 0.155 m from the vertex of the mirror (in m; answer sign and magnitude)? PLEASE ANSWER IN SCIENTIFIC NOTATION USING E

An object is placed 36 cm in front of a converging lens with a focal length of 20 cm. Draw a ray diagram.   Estimate the image distance (in cm). (Give your answer as a distance from the center of the lens.) ________ cm

Please help me with the following question and make sure your answer is correct, thanks  1. Please answer the following parts of the question Part A.  An object is placed 11 cmcm in front of a spherical mirror. The image is half as tall as the object and inverted. Determine the focal length of the mirror. Express your answer with the appropriate units.   Part B.  An object is placed 70 cm in front of a thin lens. The image is four times as tall as the object and inverted. Determine the focal length of the lens. Express your answer with the appropriate units.
