Okay kiddo, so imagine you have a toy car and you want to control it from far away so you use a remote control. The remote control sends signals to the car to tell it what to do like move forward or turn left. These signals travel through the air as waves and they have different frequencies.
Now, the frequency is how many waves or signals travel through the air in a certain amount of time. Think of it like the beat of your favorite song. Some songs have a fast beat and some have a slow beat. The frequency of the waves that are sent from the remote control to the car can also be fast or slow.
When we talk about the frequency of optimum transmission, we mean the best frequency to use so that the waves can travel as far as possible without getting weaker or losing their signal. It's like finding the perfect balance between too fast or too slow.
So, for example, if the remote control sends waves with a very low frequency, they will not travel very far and your car won't get the signal it needs to move. On the other hand, if the remote control sends waves with a very high frequency, they may not travel very far either and they may also get blocked by things like walls, trees, or other objects.
Therefore, finding the frequency of optimum transmission means using a frequency that is just right - not too high and not too low - so that the signals travel far enough and are not blocked by anything. This is important when we use things like remote controls, radios, or even cell phones so we can communicate with each other without any problems.
I hope that helps you understand frequency of optimum transmission, kiddo!
