A dental hygienist uses a small concave mirror to look at the back of a patient's tooth. If the mirror is 1.70 cm from the tooth and the magnification is 2.20, what is the mirror's focal length? (Include the sign of the value in your answer in cm.)

A mirror produces an image that is located 34.0 cm behind the mirror, when the object is located 9.70 cm in front of the mirror. (a) What is the focal length of the mirror? (b) Is the mirror concave or convex?

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 1.45m and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 4.11m, what is the focal length of the mirror? 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 mirror has the focal length equal to 0.609 m. To form a real image that is triple the size of the object on a screen, at what distance in front of the mirror should the screen be placed (in m; answer a positive number)?

When an object is placed 27.0 cm in front of a convex spherical mirror, a virtual image forms 14.5 cm behind the mirror. Determine the mirror's focal length in cm and the magnification. (a) the mirror's focal length in cm answer in cm (b) the magnification

A dental hygienist uses a small concave mirror to look at the back of a patient's tooth. If the mirror is 1.58 cm from the tooth and the magnification is 1.80, what is the mirror's focal length? (Include the sign of the value in your answer.) cm

A student notices that the image produced from a large concave mirror of a distant skyscraper (h = 106 m) is inverted and the magnitude of the height is |hi| = 1.16 m tall. The image is located d = 152 cm in front of the mirror. Numerically, what is the focal length of the mirror, f, in cm?

An object is placed 47.5 cm from a concave spherical mirror with focal length of magnitude 22.0 cm. (a) Find the location of the image. cm in front of the mirror (b) What is the magnification of the image? (c) Is the image real or virtual?
