6 Questions
Why does the part of the spoon in water look bent?
Light bends or refracts at the surface separating two mediums like water and air.
What is the term used to describe the bending of light when it travels from one medium to another?
Refraction of light.
When a refracted ray reaches our eyes, what do we see?
An image in the direction of the ray.
Where can you observe images formed by refraction around you?
In dewdrops or raindrops on leaves and flowers in a garden.
What type of images can refraction create?
Real as well as virtual images.
What is the term used to describe the images formed when light refracts through water?
Image formed by refraction.
Study Notes
Refraction of Light
- When a spoon is placed in a glass of water, the part of the spoon in water appears bent due to the bending of light at the surface separating two mediums (water and air).
- Refraction of light occurs when light travels from one medium to another, resulting in the bending of light.
- The bent light forms an image in the direction of the refracted ray, which is usually different in position and size from the original object.
Observing Refraction
- Fill a spherical bowl or jar with water and observe the formation of multiple images around the edge.
- Observe dewdrops or raindrops on leaves and flowers in a garden to see inverted and magnified images.
Types of Images Formed by Refraction
- Refraction can create both real and virtual images.
- Water droplets, such as dewdrops or raindrops, can form magnified images of objects, like the veins of leaves.
Learn about the phenomenon of light refraction in a basic science class for 7th grade. Understand why objects appear bent when immersed in water and how light bends when traveling through different mediums.
