What is the position of an image in a curved mirror if the object is 25cm from the concave mirror with a focal length of 5 cm? The formula is 1 / f = 1 / v + 1 / u. Show your work.
4.17 cm in front of the mirror
6.25 cm in front of the mirror
4.17 cm behind the mirror
6.25 cm behind the mirror
Using the formula 1/f = 1/v + 1/u, where f is the focal length, v is the image distance, and u is the object distance:
1/5 = 1/v + 1/25
1/v = 1/5 - 1/25
1/v = 0.2 - 0.04
1/v = 0.16
v = 6.25 cm
Therefore, the position of the image is 6.25 cm in front of the mirror. Answer: 6.25 cm in front of the mirror.
