JEE AdvancedPhysicsGeometrical OpticsMCQ+3 / −1
In an experiment to determine the focal length (f) of a concave mirror by the u-v method, a student places the object pin A on the principal axis at a distance x form the pole P. The student looks at the pin and its inverted image form a distance keeping his/her eye in line with PA. When the student shifts his/her eye towards left, the image appears to the right, oh the object pin. Then,
  1. A
    x<fx \lt fx<f
  2. B
    f<x<2ff \lt x \lt 2ff<x<2f
  3. C
    x=2fx = 2fx=2f
  4. D
    x>2fx \gt 2fx>2f
