An object is placed 5 cm from the pole of a concave mirror. if the focal length of the mirror is 10 cm. what is the image distance?
Answer Details
To solve this problem, we can use the mirror formula:
1/f = 1/v + 1/u
where f is the focal length of the mirror, u is the object distance (distance between the object and the mirror), and v is the image distance (distance between the image and the mirror).
Given that the object is placed 5 cm from the pole of the concave mirror and the focal length is 10 cm, we can substitute these values into the formula and solve for v:
1/10 = 1/v + 1/5
Multiplying both sides by 10v5, we get:
v = 10 cm in front of the mirror
Therefore, the answer is:
- 10 cm in front of the mirror.
