at t=T/6, total distance covered= 2*pi*r/6 and displacement= r
difference of them = 2*t
so, 2*pi*r/6- r =2(1/6)=1/3
r=1/(pi-3)=7.062
Answer:
Explanation:
Mechanical waves and electromagnetic waves are the types of waves we have. The major difference between this type of waves is that, while mechanical waves requires material medium for its propagation, electromagnetic waves does not require material medium for its propagation.
Example of mechanical waves are waves produced by a ripple tank.
Example of an electromagnetic waves are the electromagnetic spectrum which includes radio waves, infrared waves, visible light, ultraviolet rays etc... This waves are produced naturally without any medium compare to mechanical wave.
The radio waves travels between the two boxes and they were travelling through air,
- Box B captures, amplifies and demodulates radio waves.
- Box A modulates, amplifies and send out radio waves.
<h3>What are radio waves?</h3>
- Radio waves are the type of radiation from the electromagnetic spectrum.
- The radio waves can be used in communication technologies like computer, phones, radios , etc..
- Radio waves have lower frequencies but longer wavelength.
- These devices will get signal and then it transmit as mechanical waves through sound.
In that way, the radio waves from box A to B through air, the box A will gets the signal, and then modulates, amplifies and then it send out radio waves. Through the air, Box B will captures, amplifies and demodulates radio waves.
