Question

an object is placed 6 cm from a concave mirror with a focal length of 12 cm. the image is cm from the mirror? (sign /- isn't necessary)

Answer 1

The image is located 4 cm from the concave mirror.

Step-by-step explanation:

To find the image distance, we can use the mirror equation: 1/f = 1/do + 1/di , where f is the focal length, do is the object distance, and di is the image distance. In this case, the object distance (do) is 6 cm and the focal length (f) is 12 cm. Plugging in these values, we can solve for di:

1/12 = 1/6 + 1/di

Multiplying both sides by 12di, we get:

di = 4 cm

So, the image is located 4 cm from the concave mirror.
