FUN FACTS ABOUT RADIO WAVES
One of the most important discovery of mankind is radio waves as it made communication much more efficient.It is created when an electric field and magnetic field is joined.IT travels very fast at the speed of light. The radio receives radio waves in the air and converts them into an electrical signal which is then converted to sound waves and the raidio amplifier than boosts the sound waves so that people can hear the music on am/fm radios.
Fun facts of radio waves
*Maxwell in 1860 discovered radio wave, he described radio and light waves to be electromagnetism waves that wer travelling thorugh space.
Interesting Radio Waves Facts:
*Radio waves are not the single type of electromagnetic wave. Others are radar, bluetooth, ultraviolet light waves' microwaves/ x-rays and infrared.
*Wifi uses radio waves which are routed though a wireless internet router using radio waves , which ahve frequencies between 2.4 and 5.8 GHz.
*It is believed that radio waves will travel forever. Unless something absorbs the waves.
*If radio waves really travels forever then it is possible that radio waves from earth have been heard on other planets.
*Radio waves will bounce off items if not absorbed. This means radio waves can bounce off the ground or a cloud or any electric conductor object.
* The text messege which is received from one cell phone to another cell phone is a radio waves.
*Different types of radio waves helps to send messege to specific person.
*Wavelengths can reach 2 miles.
*Astronomical objects emit radio waves.
*Pictures are also created from radio waves through new developed system
*Astronomers use radio telescopes to study the radio waves being emitted from planets, dust, stars, gas clouds etc.
*RAdio waves are sinusoidal.
*Properties of radio waves changes with their wavelengths
*Radio waves can carry information in different means. for example, Amplitude modulation and frequency modulation.
*It can carry energy.
CONCLUSION
There are many fun facts about radio waves. This article can go on and on. like, radio waves can be mixed to form new frequencies according to laws of super heterodyning, Where two initial frequencies say the first is 18 Mgz called A and second is 10 Mhz called B. The result is four product frequency and the original A and B and the two new frequencies are A+B(8 Mhz) and A-B(8 Mhz). To know mroe anyone can google it. There are a lot complex things which are unknown to you, to me may be few are also unknown to the scientists as well about radio waves.
