Chapter Name: Reflection of Light
Activity Name: Image through vehicle mirror in Reflection of Light
This experiment aims to compare the images formed by a plane mirror and a rearview mirror in a vehicle. By observing the reflections in both mirrors, we will explore the differences in the size and characteristics of the images formed.
- Plane mirror
- Vehicle with a rearview mirror
Step by Step Procedure:
- Obtain a plane mirror.
- Find a vehicle with a rearview mirror.
- Position yourself in front of the plane mirror and observe your image.
- Now, sit in the vehicle and observe your image in the rearview mirror.
- Compare the images seen in both mirrors.
- The image seen in the plane mirror appears to be of the same size as the actual object.
- The image seen in the rearview mirror of the vehicle appears smaller compared to the actual object and the image seen in the plane mirror.
- Handle the mirrors with care to avoid any damage or scratches.
- Ensure that the mirrors are clean and free from any dirt or smudges before conducting the experiment.
- Avoid looking directly into bright sunlight or headlights while performing observations in the rearview mirror to protect your eyes.
Lesson Learnt from Experiment:
Through this experiment, we learn that the image formed in a plane mirror is of the same size as the object, while the image formed in a rearview mirror appears smaller.
The difference lies in the curvature of the rearview mirror, which is convex, whereas the plane mirror has a flat surface. The convex shape of the rearview mirror allows a wider field of view, which enables the driver to see a larger area behind the vehicle despite the smaller apparent size of the objects in the reflection.
