WebRadio Waves and Microwaves. Some important properties of radio waves and microwaves are: They are reflected by metal surfaces. They heat materials if they can make particles in the material vibrate. The amount of heating depends on the power of the radiation and the time that the material is exposed to the radiation. Radio Waves and Microwaves. 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 ...

WebThe microwave oven cooks food by using high frequency electromagnetic waves (part of the electromagnetic spectrum - so their speed is 3 x 10 8 m/s in a vacuum) called microwaves at 2.45 GHz. The wavelength of mircowaves are between 1 millimetre and 30 centimetres. Try calculating the wavelength of microwave oven microwaves! 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.
