Light Basics
Light is something we can see, and it comes from different sources like the Sun, light bulbs, and candles. It doesn't need air to travel and always moves in a straight line.
What is Reflection?
Reflection happens when light bounces off a smooth surface like a mirror. This is how we see images in the mirror.
Types of Reflection
There are two main types:
Regular Reflection: This happens on smooth surfaces like mirrors. The image is clear and sharp.
Irregular or Diffused Reflection: This happens on rough surfaces like walls. The image is not clear.
Why Images Look Flipped in Mirrors
In mirrors, the right side of things appears on the left and vice versa. That's why words like 'AMBULANCE' are written in a special way, so drivers can read them correctly in their rear-view mirrors.
Spherical Mirrors
These mirrors are curved. There are two types:
Concave Mirror: These mirrors are used to make things look bigger. Dentists and doctors use them.
Convex Mirror: These mirrors show a larger area and are used as rear-view mirrors in cars.
Lenses
Lenses bend light. There are two main types:
Concave Lens: These lenses spread light out and are used to help people who can't see things far away.
Convex Lens: These lenses bring light together and are used to make things look bigger.
What Lenses are Used For
Lenses are found in things like cameras, telescopes, and glasses.
Dispersion of Light
When light passes through a prism or raindrops, it breaks into colors like in a rainbow.
