Activity Description:

How to form multiple images? in Reflection of Light - Class 7 Science Experiment

In this experiment, you will explore how to form multiple images using two plain mirrors joined together at a certain angle. By placing an object between the mirrors and adjusting the angle, you can observe multiple reflections of the object.

Required Items:

  1. Two plain mirrors of the same size
  2. Cellophane tape
  3. An object to be used as the subject for reflection

Step by Step Procedure:

  1. Take the two plain mirrors and join them together using cellophane tape. Ensure that they are aligned parallel to each other and can be folded like a book.
  2. Place the combined mirrors on a flat surface or hold them with your hands.
  3. Choose an object to be the subject of reflection and place it between the mirrors. Make sure the object is upright and positioned at the center between the mirrors.
  4. Adjust the angle between the mirrors by carefully folding them. You can experiment with different angles to see various reflections.

Experiment Observations:

  • Count the number of images of the object that you can see as you change the angle between the mirrors. Each mirror will produce one reflection, and the number of reflections will depend on the angle between the mirrors.

Precautions:

  1. Handle the mirrors with care to avoid any cracks or breakage.
  2. Be cautious while adjusting the angle between the mirrors to prevent any injuries or damage to the mirrors.
  3. Ensure the object used for reflection is not fragile or valuable, as accidents may happen during the experiment.

Lesson Learnt from Experiment:

Through this experiment, you will discover that the number of images produced depends on the angle between the mirrors. With each change in the angle, you will observe additional reflections of the object. Understanding this concept helps in comprehending the behavior of light during reflection.
