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 ...
WebInfrared and microwaves are two types of electromagnetic radiation. (a)€€€€State one example of the use of each type of radiation for communication. Infrared: _____ Microwaves: _____ (2) 1. (b)€€€€Some of the properties of infrared and microwaves are the same. State two of these properties. 1. WebMicrowaves are sometimes considered to be very short radio waves (highfrequency and high-energy radio waves). Some important properties of microwaves are: They are reflected by metal surfaces. They heat materials if they can make atoms or molecules in the material vibrate. The amount of heating depends on the intensity of the microwave ...

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. They are also all members of the electromagnetic spectrum and some of them can be used for communication. For the exam you should know some typical examples of how and where they are used, and any associated hazards.
