Question

In an experiment to determine the focal length (f) of a concave mirror by the u - v method, a student places the object pin O on the principal axis at a distance x from the pole P. The student looks at the pin and its inverted image at I on principal axis from a distance keeping his/her eye in line with PO. When the student shifts his/her eye towards left, the image appears to the right of the object pin. Then,

Choices

Choice (4) Response

a.

x>2f

b.

x<f

c.

x=2f

d.

f<x<2f
