By changing the known variables in the aforementioned equation, we obtain,
- 1/v = 1/15 - (-1/10)
- 1/v= 1/15 + 1/10
- 1/v = (2 + 3)/30 (LCM)
- v = 5/30
- v = 6cm
The virtual image is created behind the mirror.
The type of image that was created
- When the v is positive, the image is formed inside the mirror, and when the v is negative, the image is formed in front of the mirror.
- This shows that, in this case, the image is created within the mirror at a distance of 6 cm from the mirror's pole.
- The resulting image is genuine when v is negative; it is virtual when v is positive.
An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image.
A convex mirror with a focal length of 15 cm is placed 10 cm away from an object. The picture is virtual in nature and is positioned behind the mirror. v is positive which means that the image is formed inside the mirror.
