Answer:
Refraction has a lot of applications in optics and technology. The refraction phenomenon is regularly connected with light but can also be applied to other waves such as sound or water.
Explanation:
Examples of Reflection :
- Meters like ammeters and voltmeters use a mirror to avoid parallax error.
- The wing and rear-view mirrors of a car are made of a convex and a plane mirror respectively. The two wing mirrors enable the driver to see objects on both sides of the car. The rear-view mirror enables the driver to see things behind the car.
- A microscope uses a mirror to reflect light to the specimen under the microscope
- An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece.
- An overhead projector as in figure uses a concave mirror to reflect light from the object to the screen.
Examples of Refraction :
- Spectacles are worn by people with defects of vision use refraction for providing correct vision.
- Refraction is used in the working of telescopes, microscopes, peepholes of house doors, cameras, movie projectors, magnifying glasses, etc.
- Refraction is responsible for the formation of a mirage and other optical illusions.
