How does the satellite dishes works.
As we live in the world of technology dishes place a major role of providing channel for the customer but do you know how this satellite dishes works? Today am taking about thos topic let's begin.
To understand the working of satellite dishes you need to understand one principal of formation of image of a concave mirror . When an object is placed at infinity the image is formed at focus and the size of the image is very small and it is real and inverted. The rays coming from the satellite which is at far distance is considered to be parellel so when a parellel ray comes to the surface of concave mirror it gets reflected trough the focus of the mirror.
Now a satellite dish contains a concave parabolic surface and a antenna is attached to it . The antenna is at the position of focus so when the the parellel rays coming from the satellite gets reflected to focus for a strong signals to be captured at the
antenna. The antenna is then connected to your set top box where it analysis the signals and you can see your favourite TV channels.
So this is how the satellite dish works . I hope you understand see you soon and good bie.
