How are microwaves used in communication? – Sage-Answer

Web24 feb. 2024 · Satellite transmissions - Microwaves can pass easily through the Earth's atmosphere (radio waves can't do this). Therefore, they can also be used to send and receive information from the satellites. Phones use for communication; signals are sent to the satellite and then passed on to their destination. Wifi also uses microwaves. WebUVC is germicidal, destroying bacteria, viruses and moulds in the air, in water and on surfaces.

Web21 aug. 2024 · Microwaves are the combination of radio waves and infrared radiation on the electromagnetic spectrum. These microwaves help in heating the food properly in accurate temperature. These waves contain profound property, these waves are absorbed by water, fats, and sugar which in-turn converts into atomic motion i.e., heat. WebAs a result of this, the danger associated with EM waves increases along with the frequency. The shorter the wavelength, the more ionising the radiation. Although the intensity of a wave also plays a very important role. Ultraviolet, X-rays and gamma rays can all ionise atoms. In general, electromagnetic waves become more dangerous the shorter ...

When you send a message, voice call, a video clip, or a photo, this information is transformed into signals which are then sent through microwaves to the nearest cell tower.

WebRotate the receiver in 5° increments, and record its reading for angles between 0° and 90° in the “Data” section. Since the meter measures the relative electric-field amplitude of the microwaves, you must square all readings to obtain the relative intensity I. Plot the experimental values of I as a function of θ.

WebRadio waves, microwaves, infrared, visible light, ultraviolet light, X-rays and gamma rays are all transverse waves.
