  • Hold the concave mirror in your right hand and select a distant object (a candle in this case). The selected object should be visible with your naked eyes.
  • Adjust the position of the screen in such a way that it forms a clear image of the candle on the screen.
  • Measure the distance between the concave mirror and the screen with a metre scale.
  • Repeat the experiment two or three times.​

 Procedure( As performed in the simulator)

  • Drag the screen by clicking on point A of the screen till you get a sharp image of the object.
