what type of electromagnetic radiation can radio telescopes detect?

Radio telescopes detect radio waves coming from space. Although they are usually very large and expensive, these telescopes have an advantage over optical telescopes. They can be used in bad weather because the radio waves are not blocked by clouds as they pass through the atmosphere.

In everyday life we encounter radio, microwaves, infrared, ultraviolet, and visible light waves. We usually don't experience X-rays, and very rarely gamma rays. Radio waves come from communication devices as well as interstellar radiation. Microwaves typically would be found in a microwave.

One way to make RF waves visible is with something like a radio telescope. An ordinary (light) telescope collects light and focuses it onto a receptor (CCD, photographic plate, the eye), thus making it possible to see the visible radiation emitted by a distant galaxy.

The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. You know more about the electromagnetic spectrum than you may think.

Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.

Millimeter wave machines use non-ionizing radiofrequency waves to detect threats. The machine bounces the waves off the body and back to the machine. Millimeter wave scanners emit far less energy than a cell phone.

Cameras measure electromagnetic energy, but un- like an ideal radio receiving antenna that one might connect to a spectrum analyzer, a camera measures electromagnetic radiation only within a certain region of the electromagnetic spectrum.

We use radios, x- rays, TV, radio telescopes now in radios they use radio waves which are the longest wavelength in the electromagnetic spectrum. Radio waves also carry signal for your television and cell phones.

The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects.

Electromagnetic waves include radio, visible light, x-ray, gamma rays, and cosmic waves. Electromagnetic wave spectrum, microscopes can use more than just light! Electromagnetic waves are considered transverse waves which is a “flip-flopping” of positive and negative dipoles of particles.

Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices. EM exhibits a dual wave and particle nature.

This light, however, is only one type of electromagnetic radiation. Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum. The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.

Answer Expert Verified The part of the electromagnetic spectrum closest to radio waves is microwaves. The wavelength of radio waves ranges from 10 cm to more than 1 km.

Most objects in space give off (radiate) light. This light is given different names, depending on its wavelength and energy – radio waves (long wavelength, low energy), microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays (short wavelength, high energy).

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays. The part of the electromagnetic spectrum that we are able to see is the visible light spectrum.

Electromagnetic (EM) radiation is a stream of photons, traveling in waves. ... Low-energy photons (such as radio) behave like waves, while high-energy photons (such as X-rays) behave more like particles. You can read more about how photons work in How Florescent Lamps Work. EM radiation can travel through empty space.
