Answer:
1. 12 cm
2. 0.133 m
3. 0.03 m
4. Plane mirror
Virtual image
Upright
Behind the mirror
The same size as the object
Concave mirror when the object is located a distance greater than the focal length from the mirror's surface
Real image
Inverted image
In front of the the mirror
Diminished when the object is beyond the center of curvature
Same size as object when the object is placed at the center of curvature
Enlarged when the object is placed between the center of curvature of the mirror and the focus of the mirror
Concave mirror when the object is located a distance less than the focal length from the mirror's surface
Virtual image
Upright image
Behind the the mirror
Enlarged
Convex mirror
Type = Virtual image
Appearance = Upright image
Placement = Behind the mirror
Size = Smaller than the object
Explanation:
1. For plane mirror, since there is no magnification, the virtual image distance from the mirror = object distance from the mirror = 12 cm behind the mirror
2. The height of the object = 0.3 m
The distance of the object from the mirror = 0.4 meters
Height of image formed = 0.1 meter
We have;
Image distance from the mirror = 0.1/0.3×0.4 = 2/15 = 0.133 m
Image distance from the mirror = 0.133 m
3.
The image height = 0.06/0.2×0.1 = 3/100 = 0.03 meter
The image height = 0.03 meter
4. Plane mirror
Type = Virtual image
Appearance = Upright image with the left transformed to right
Placement = Behind the mirror
Size = The same size as the object
Concave mirror when the object is located a distance greater than the focal length from the mirror's surface
Type = Real image
Appearance = Inverted image
Placement = In front of the the mirror
Size = Diminished when the object is beyond the center of curvature
Same size as object when the object is placed at the center of curvature
Enlarged when the object is placed between the center of curvature of the mirror and the focus of the mirror
Concave mirror when the object is located a distance less than the focal length from the mirror's surface
Type = Virtual image
Appearance = Upright image
Placement = Behind the the mirror
Size = Enlarged
Convex mirror
Type = Virtual image
Appearance = Upright image
Placement = Behind the mirror
Size = Smaller than the object.
