Radiowaves are the electromagnetic waves of frequency range from 5xx10^5Hz to 3xx10^9Hz. These waves are produced by oscillating electric circuits having an inductor and capacitor.

Electromagnetic waves, as the name suggests, are a type of wave that oscillates between electric and magnetic waves. Electromagnetic waves can travel in a vacuum, unlike sound waves, for example, which require a material medium for propagation. Clear examples of electr...
(ii) Why are infrared waves referred to as heat waves ? How are they produced ? What role do they play in maintaining earth.s warmth through the greenhouse effect ? View Solution The part of electromagnetic spectrum referred as heat wave is ...
Radio waves are electromagnetic radiation that constantly bombards your home from every direction, all day, every day. These waves are harmless and pose no risk to your health, but they can be annoying if you want complete privacy in your home. ...
By using more than one antenna, data through radio signals can be boosted by as much as a factor of three, scientists have discovered. All products featured on Wired are independently selected by our editors. However, we may receive compensation from retailers and/or from purchases of products...
Light waves travel 300,000 kilometers (186,000 miles) per second! They can also travel through a vacuum. That is why light from the sun and distant stars can travel through space to the earth! Soils There are many different kinds of soils. Different soils have different types of rock ...
A fast radio burst from 8 billion light years away is near the limit of what modern radio telescopes can detect, but Ryder and his colleagues expect the next generation of telescopes to be able to spot even older, more distant FRBs. ...
Infrared waves, or IR radiation, is a type of electromagnetic radiation that has a wavelength greater than the wavelengths in the visible part of the electromagnetic spectrum; they are located adjacent to visible region and the microwave region at its other end. Infrared radiation can be emitted ...
You can also run the rf-ping command to check the strength of radio signals received by a STA. If the value of RSSI is lower than –65 dBm, the radio signals received by the STA are weak. If the strength of signals received by the STA is poor, perform the following operations...
