In spherical lenses, all distance are measured from ___________.

All the distances are measured from the ………….. Of the lens.

According to Cartesian sign conventions all distances are measured from the __________.

What will be focal length of a spherical mirror if distance of object from the mirror is (30 pm 0.5)cm and distance of image from the mirror is (10 pm 0.2) cm ?

A short linear object of length L lies on the axis of a spherical mirror of focal length f at a distance K from the mirror. Calculate the axial length of the image.

In case of a spherical mirror show how magnification (m) depends on focal length (f) of the mirror and image distance (v).

Statement I : Focal length of a spherical mirror depends on the distances of object and image from the mirror. Statement II : (1)/(f ) = (1)/(v ) + (1)/(u)
