What is a radio galaxy?
A radio galaxy is anactive galaxy that is very luminous at radio wavelengths (between 10 MHz and 100 GHz). The radio emission is due to the "synchrotron process" which is caused by the acceleration of charged particles, near the speed of light) through magnetic fields.
Is a radio galaxy very dense?
no
What are Wavelengths that are short and very high energy called?
Radio waves
What are the different wavelengths?
The electromagnetic spectrum consists of various types of electromagnetic radiation, each characterized by a different wavelength. It includes gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves. These wavelengths range from very short (gamma rays) to very long (radio waves).
What is electromagnetic's relative wavelength?
The electromagnetic spectrum encompasses a wide range of wavelengths, from very long radio waves with wavelengths of kilometers to very short gamma rays with wavelengths less than the size of an atomic nucleus. The specific wavelength of electromagnetic radiation depends on the specific type of wave being considered.
Is Mars luminous or not?
It can be with the light it reflects from the sun, but not over long distances. Mars does not emit light except in the very long wavelengths (infra red). It is non-luminous. It is only visible because of the light it reflects, as the first answer states.
Radio waves are radiation with very long what?
Radio waves are electromagnetic radiation with very long wavelengths, ranging from about 1 millimeter to over 100 kilometers. They are used for various communication purposes, such as broadcasting, cellular networks, and WiFi.
Radio waves have longer wavelengths than xrays?
Yes, radio waves have longer wavelengths (measured in meters) and lower frequencies compared to x-rays, which have shorter wavelengths (measured in nanometers) and higher frequencies. Radio waves are used for communication and broadcasting, while x-rays are used in medical imaging and security screening due to their ability to penetrate solid objects.
What does vhf stand for?
VHF = "Very High Frequency" Formally, radio frequencies from 30 MHz to 300 MHz. (Wavelengths between 1 meter and 10 meters)
Are microwaves radio waves?
Yes and No All waves like that or electomagnetic waves that are the same thing but just operate on different frequencies and wavelengths But not microwaves are as much radio waves as they transmit heat signatures are well as slight audio signature Essentially no but they are very similar microwaves are just faster and at a different wavelengths
What is the wavelength range of the EM spectrum?
The electromagnetic spectrum includes wavelengths ranging from very short gamma rays and X-rays to very long radio waves. The overall range is from approximately 10^(-14) meters for gamma rays to 10^6 meters for radio waves.
Why do radio telescopes have to be very large in order to effectively capture and study radio waves from space?
Radio telescopes have to be very large in order to effectively capture and study radio waves from space because radio waves have long wavelengths and low energy, requiring a large collecting area to gather enough of them for analysis. The larger the telescope, the more radio waves it can collect, allowing for more detailed and accurate observations of celestial objects.
