A convex mirror with a radius of curvature of -31.0 cm is used to form an image of an arrow that is 13.8 cm away from the mirror. If the arrow is 1.70 cm tall and inverted (pointing below the optical axis), what is the height of the arrow's image? (Include the sign of the value in your answer.)

Step 1
We can use the mirror formula to find the focal length (f) of the mirror. 1/f = 1/v - 1/u where f is the focal length, v is the image distance, and u is the object distance. Given that the image distance (v) is 13 cm and the object distance (u) is unknown, we can Show more…

The image produced by a concave mirror is located 22.3 cm in front of the mirror. The focal length of the mirror is 10.1 cm. How far in front of the mirror is the object located (in cm)?

A convex mirror with a radius of curvature of -32.0 cm is used to form an image of an arrow that is 13.6 cm away from the mirror. If the arrow is 1.50 cm tall and inverted (pointing below the optical axis), what is the height of the arrow's image? (Include the sign of the value in your answer.)

An object is 33 cm in front of a convex mirror with a focal length of -17 cm. Part A: Use ray tracing to determine the position of the image. Express your answer to two significant figures and include the appropriate units. Part B: Is the image upright or inverted? The image is upright. The image is inverted.
