MCQ
For observing a cricket match, a binocular is preferred to a terrestrial telescope because
  • ✓
    The binocular gives the proper three dimensional view
  • B
    The binocular has shorter length
  • C
    The telescope does not give erect image
  • D
    Telescope have chromatic aberrations
✓
