Radio Transmission Radio waves are useful for transmitting data over long distances through air medium as it uses radio signals for transmission. Radio waves are broadcasted with Amplitude Modulation and Frequency Modulation schemes which use antennas. To travel long distances, AM radio signals use the lower carrier in frequencies which is higher than FM broadcasting but lacks sound quality at the receiver end whereas AM signals have better bandwidth which produces good sound quality and supports stereo signals during transmission. The radio waves used during transmission are omnidirectional, so signals can be propagated through all directions which provides a higher ... Read More

Radon and Radium are two elements in the periodic table that are often associated with each other due to their similar properties and radioactive nature. However, there are several differences between the two elements, including their physical and chemical properties, occurrence in nature, and health effects. What is Radon? Radon is a radioactive gas that is a byproduct of the decay of radium. It is part of the decay series in which uranium decays into multiple elements until reaching the stable element, lead. Radon decays into polonium and alpha particles. The longest-lived isotope of radon is radon-222 which has a ... Read More

MRI and fMRI are used to produce images of the body using magnetic fields and radio waves. MRI creates structural images of the body. where fMRI creates functional images of the brain. The manner in which they are used is another difference. While fMRI is largely used for research, MRI is mostly used for diagnostic purposes. Read this article to find out more about MRI and fMRI and how they are different from each other. What is MRI? MRI uses MRS (Magnetic Resonance Spectroscopy) technology to measure the specific chemical biomarkers that are present inside your body. A sizing magnet, ... Read More
