Longer radio waves, specifically those in the low frequency (LF) and medium frequency (MF) ranges, are generally less affected by static and atmospheric noise compared to higher frequency waves. These lower frequencies can diffract around obstacles and travel longer distances, making them more resilient to interference. Additionally, frequencies below 30 MHz are typically less impacted by static from lightning and other natural sources.
Radio waves will disturb matter which is more or less on the order of magnitude of the wavelength of the waves.
No, he did not, but he was certainly important in radio's growth and development. Edwin Howard Armstrong invented what we today know as FM radio. (Early radio used only the AM process to add sound to a radio wave.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.
Microwaves are radio waves. That name is given to radio waves atfrequencies above 3 GHz (wavelength less than 10 centimeters).
FM radio is inherently less sensitive to natural noise ... not immunebut significantly less sensitive ... than AM radio is.
AM - Amplitude Modulation FM - Frequency Modulation AM radio is simply lower frequency sound waves caused from the transmitter. This can cause the sound to become very soft or loud at stages. Static sound can also me heard from house hold appliances interfering with the Radio. The quality of the Radio can be heard less better than FM.
I dont think they do, Radio waves diffract less and arn't affected by the ionosphere which is the upper part of the atmosphere. Most electromagnetic waves are affected severely by the atmosphere, which is a good thing due to the strength they carry EXCEPT microwaves *Apparantly*.

Waves with lower frequency: for example radio waves.
Radio waves with wavelengths less than a meter include micro-waves, terahertz waves, and millimeter waves. These waves are commonly used in various applications such as wireless communication, radar systems, and medical imaging.

Edwin Howard Armstrong invented several things, but he is best known for inventing what we today know as FM radio. (Early radio was only on the AM band.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.

FM radio works like light. If a shadow is made (something in the way) , you get less light. Radio waves work in a straight line. If something is in the way, less radio waves. The rule is broken here if you use Am radio waves. Low clouds can make the waves bounce between the clouds and the ground and can travel as far as 1000 miles or further. So the answer is yes.
Microwaves have more energy than radio waves. They have shorter wavelengths and higher frequencies, which results in more energy being carried by microwaves compared to radio waves.
AM radio waves have longer wavelengths compared to FM radio waves. This means that AM waves are better able to diffract around obstacles and travel farther distances. FM radio waves, with their shorter wavelengths, are less prone to diffraction and tend to travel in straight lines, making them more susceptible to obstacles blocking their path.
