Visible light
radio
Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.
The waves with higher frequencies have more energy and the gamma rays have the most energy in the electromagnetic spectrum
No, its just visible light - light is part of the electromagnetic spectrum and is in the middle of it.
Radio waves
Could it be that the frequency of sound waves are to low?
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
I think in the ultraviolet region of the electromagnetic spectrum.
We call that the visible or optical spectrum.
the electromagnetic spectrum is reflected by different things like TVs and glass
no they are not. NASA suggests that the spectrum of electromagnetic radiation does not include cosmic rays.
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
