Chapter Name: Refraction of Light At Plane Surfaces
Activity Name: Reflected image in the wall in Refraction of Light At Plane Surfaces
This experiment explores the phenomenon of seeing a reflected image on a wall when a bright metal object is placed near one end of a long wall facing the Sun.
- Bright metal object
- Long wall (approximately 30 feet in length)
Step by Step Procedure:
- Go to one end of the long wall facing the Sun.
- Ask your friend to stand at the other end of the wall, holding the bright metal object.
- Position the metal object a few inches away from the wall.
- Observe the metal object and the wall from your end.
- As the bright metal object is brought closer to the wall, a distorted image of the object appears on the wall’s surface. This reflected image appears as though the wall were a mirror.
- Be cautious while observing the Sun and avoid direct exposure to sunlight to protect your eyes.
- Ensure the metal object is securely held and doesn’t accidentally fall or cause any harm.
Lesson Learnt from Experiment:
The experiment demonstrates the phenomenon of reflection of light. When light rays from the bright metal object fall on the wall’s surface, they bounce off the wall and form an image of the object. This reflected image is visible to an observer standing at a certain angle from the wall.
