Question

observe your image on a plane mirror,concave surface and a convex surface .list your observations

Answer 1

Observations in Plane Mirror:

• Image is virtual.
• Image is same size as that of the object.
• Image is erect.
• Image is neither magnified nor diminished.

Observation in Concave Mirror:

• When object is within focus: A virtual, erect and magnified image is produced behind the mirror.

• When object is inbetween focus and centre of curvature: A real, inverted magnified image is produced beyond centre of curvature.

• When object is placed beyond centre of curvature: A real, inverted diminished image is produced in between centre of curvature and focus.

Observation in Convex Mirror:

• Irrespective of the position of the object the images are always virtual, erect and diminished.
