stars in the elctro magnetic spectrum causing isotopes to minipulate
Yes, that is correct.
you look in the sky or use telescopes
No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.
Ability to detect radio waves is not a property of optical telescopes. Optical telescopes are designed to detect and focus visible light to form images of distant objects in space. Radio telescopes, on the other hand, are specifically designed to detect and study radio waves emitted by celestial objects.
Telescopes can not detect any radiation for which they were not specifically built. For example, a radio telescope is specifically designed to detect radio waves. Also, telescopes can not detect radiation that is too faint for them. What is too faint depends on the capabilities of the telescope.
You can't use spectrometers to detect black holes. Telescopes are the only way to detect them.
They detect waves coming off of the closest stars
To detect different wavelengths of the electromagnetic spectrum.
There are telescopes used to detect radio waves and others to detect infrared radiation.
Radio telescopes detect stars known as 'Pulsars'. They're very small and also known as neutron stars.
No, radio telescopes and refracting telescopes have different designs and functions. Radio telescopes are designed to detect radio waves from space, whereas refracting telescopes use lenses to bend light to create images of distant objects. While both types of telescopes have a common goal of observing the universe, their designs are optimized for different wavelengths of electromagnetic radiation.
