  • image is real, smaller and upside down
  • image is virtual, smaller and upside down
  • image is real, bigger and upright
Q.2
Image above the principal axis (PA) is
  • virtual
  • real
  • upright
  • upside down
Q.3
Image behind the mirror is
  • virtual
  • real
  • upside down
  • upright
Q.4
The 2 reflected rays that meet.
  • ray of incident
  • reflected image is produced
  • focal point
  • image is not produced
Q.5
A concave lens has focal length ofcm. At what distance from the lens a 5 cm tall object be placed so that it forms an image atcm from the lens? Also calculate the size of the image formed.
  • u=-60; h' =(5/4)
  • u=-60; h' =(4/5)
  • u= +60; h' =(5/4)
  • u=+60; h' =(4/5)
Q.6
A ray of light is travelling from a rarer medium to a denser medium. While entering the denser medium at the point of incidence, it:
  • goes straight into the second medium
  • bends towards the normal
  • bends away from the normal
  • does not enter at all
Q.7
A point object is placed at a distance ofcm from a convex mirror of focal lengthcm. The image will form at:
  • at infinity
  • at focus
  • at pole
  • behind the mirror.
Q.8

  • A convex lens has 4 dioptre power having a focal length 0.25 m
  • A convex lens has -4 dioptre power having a focal length 0.25 m
  • A concave lens has 4 dioptre power having a focal length 0.25 m
  • A concave lens has – 4 dioptre having a focal 0.25 m
