Part A A concave cosmetic mirror has a focal length of 30 cm. A 5.0-cm-long mascara brush is held upright 15 cm from the mirror. Use ray tracing to determine the location of its image. Express your answer to two significant figures and include the appropriate units. Enter a positive value if the image is on the other side from the lens and a negative value if the image is on the same side. Value Units Submit Request Answer Part B What is the height of the image? Use ray tracing to determine. Express your answer to two significant figures and include the appropriate units.

Problem 26.36 A concave mirror produces a virtual image that is three times as tall as the object. Part A If the object is 12 cm in front of the mirror, what is the image distance? Express your answer using two significant figures. di = -36 cm Part B What is the focal length of this mirror? Express your answer using two significant figures. f = 0.06 cm
