Question

if m is magnification of image of real object value of m is smaller than 1 and positive then the image formed due to​

Answer 1

Image is inverted and real, and smaller than the object.

Step-by-step explanation:

If the magnification is less than 1, then the image formed is inverted and real as size of image is smaller than the size of object.

Such an image is formed when object is placed between optical center and focus of curvature of lens or mirror.

Sign convention are as follows:

• We draw diagrams such that incident light travels from left to right.
• Distances are measured from the pole of the mirror/lens.
• Positive distances are those that are measured in the direction of the incident ray.
• Distances in the direction opposite to that of the incident ray are considered negative distances.
• Heights are positive when measured upwards and perpendicular to principle axis.
• Heights are negative when measured downwards and perpendicular to principle axis.
• Focal length and radius of curvature are negative for concave mirror and positive for convex mirror.
• Focal length is positive for convex lens and negative for concave lens.
