How do you appreciate the use of reflection of light by a concave mirror in making of TV antenna dishes ?
- T.V antenna dishes contain concave surface to receive the signals from the distinct communication satellites.
- The concave shape of a dish antenna helps to reflect the signal to the focal point of the dish.
- A device known as feed horn is mounted at the focal point which gathers the signals and sends the to a processing unit.
- Hence I appreciate the working process of T.V. antenna dishes.
