An object is 15 cm in front of a concave mirror having radius of curvature of R=10 cm. Use ray tracing to determine the location of the image (in cm). Don't include units in your answer.

An object is placed 30 cm in front of a converging mirror having a focal length of magnitude 20 cm. What is the image distance, in cm?  Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.   An object is placed 30 cm in front of a diverging mirror having a focal length of magnitude 20 cm.

Chapter 34, Problem 041 A lens is made of a transparent material having an index of refraction of 1.70. One side of the lens is flat, and the other convex with a radius of curvature of 27.0 cm. (a) Find the focal length of the lens. (b) If an object is placed 51.0 cm in front of the lens, where will the image be located? (a) Number Units (b) Number Units

A student notices that the image produced from a large concave mirror of a distant skyscraper of height hs= 106 m is inverted and the magnitude of the height is |hiI = 1.46 m tall. The image is located di = 178 cm in front of the mirror. A)Write an expression for the distance between the mirror and the skyscraper, ds. B) What is the distance between the mirror and the skyscraper in meters? C) What is the focal length of the mirror, f, in centimeters?
