Chapter Name: Light, Shadows and images
Activity Name: Fun with a magnifying lens in Light, Shadows and images
In this experiment, you will use a magnifying lens to form an image of a tree on a white drawing sheet. You will compare the image formed through the magnifying lens with the image formed through a pinhole camera.
- Magnifying lens
- White drawing sheet
- Tree or object to be imaged
- Light source
Step by Step Procedure:
- Set up your experiment in a well-lit area.
- Place the white drawing sheet on a flat surface.
- Position the tree or object you want to image in front of the white drawing sheet.
- Hold the magnifying lens between the object and the white drawing sheet, making sure it is a few inches away from the object.
- Adjust the position of the magnifying lens until you see a clear and focused image of the tree on the white drawing sheet. You may need to move the lens closer or farther from the object to achieve a clear image.
- Once you have a clear image, observe the characteristics of the image formed on the sheet.
- The image formed on the white drawing sheet will be inverted, meaning it will be upside down compared to the actual tree.
- The image formed through the magnifying lens will be clearer than the image formed with a pinhole camera.
- Handle the magnifying lens with care to avoid any damage.
- Ensure the light source is bright enough to create a clear image.
- Do not look directly at the sun or any other intense light source through the magnifying lens, as it can cause eye damage.
Lesson Learnt from Experiment:
Through this experiment, you have observed that the image formed by a magnifying lens is inverted on the white drawing sheet. Additionally, you have noticed that the image formed through the magnifying lens is clearer than the image formed with a pinhole camera.
This demonstrates the ability of a magnifying lens to gather and focus more light, resulting in a sharper image. Understanding the behavior of light and the properties of lenses can help us comprehend how images are formed and how optical devices function.
