Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.
importance of voice modulation in radio
wastage of time....they cannot concentrate their study.....
Yes, it is a technique used in radiology to visualize internal structures of the body in detail.
The dimensions of the antenna completely depend on the frequency band in which youplan to operate the radio. This is all covered in the study materials for the license exam.You do have a license to operate that transmitter, don't you ? ! ?

No. Modern-day astronomers do not use only visible electromagnetic radiation to study space. They use additional bands of the electromagnetic spectrum to study space, including radio, microwave, infra-red, ultraviolet, X-ray, and gamma ray. Darn! That's just about everything.
White light, which can split in to the colours is part of the electromagnetic spectrum. Other parts of the electromagnetic spectrum are, cosmic rays, X-rays, UV light, infra red(IR) waves, micro waves, and radio waves. m ic ray of the spectrum
All the types on the electromagnetic spectrum (e.g. infrared, ultraviolet, visible, radio, etc.)
The Arecibo telescope can detect radio waves in the electromagnetic spectrum. It operates at radio frequencies between 300 MHz to 10 GHz, allowing it to study objects such as pulsars, galaxies, and the Earth's atmosphere.
The biggest telescopes on Earth typically operate in the optical and infrared parts of the electromagnetic spectrum. These telescopes are used to study a wide range of celestial objects, from planets and stars to galaxies and quasars.
Ground based astronomers utilize the optical and radio regions of the electromagnetic spectrum. Optical wavelengths provide high-resolution images of celestial objects, while radio wavelengths help study objects that emit radio waves, such as galaxies and pulsars. By combining observations from both regions, astronomers can gain a more complete understanding of the universe.
The discovery that stars emit energy across the entire electromagnetic spectrum led to innovations in astrophysics, including advancements in the understanding of stellar evolution, the development of space telescopes capable of capturing various wavelengths of light, and the ability to study celestial objects and phenomena in greater detail.

radio astronomy
The visible light portion of the electromagnetic spectrum would be used to study waves that humans can see. This portion of the spectrum includes colors ranging from red to violet and is the only part of the spectrum visible to the human eye.
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
No, astronomers also use other forms of electromagnetic radiation, such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, to study space. Different wavelengths provide unique insights into different processes occurring in the universe.
