Answer:
The image will be formed at a distance of 22.5 cm from
the mirror.
Nature of image: Real, inverted
Explanation:
Since it is given that the mirror is converging, thus it is a concave mirror
Radius of curvature = 30 cm
Focal length = R/2
= 30/2
= 15 cm
_________________________
In a concave mirror, we have
→ u = -45 cm
→ f = -15 cm
According to mirror formula :
1/v=1/u=1/f
▪︎ 1/v=1/f-1/u
▪︎ 1/v = (1/-15) - (1/-45)
▪︎ 1/v =(-1/15) - (-1/45)
▪︎1/v=-2/45
▪︎45 =-2v
▪︎v=45/-2
▪︎v=-22.5 cm
[Here, -ve sign indicates that the image is formed in front of the mirror.]
