Electromagnetic spectrum is made up of wide range of frequencies which range from few Hertz (cycles per second) to several TeraHertz. In most books, electromagnetic spectrum is marked with help of wavelengths. Wavelength is measured by speed of light divided by the frequency.
The electromagnetic spectrum contains several types of energy, including radio waves, microwaves, infrared radiation, visible light, ultraviolet light, X-rays, and gamma rays. Each type of energy has different wavelengths and frequencies, providing a wide range of uses in various fields.
Radio waves have the longest wavelength in the electromagnetic spectrum, ranging from several meters to kilometers in length.
Radio waves have the longest wavelengths in the electromagnetic spectrum
That would be what we call "radio" waves.Although, to the extent that there is E&M radiation from ordinary utility transmission lines, that would have a wavelength much longer than any radio communication. 60 Hz corresponds to a wavelength of something like 3,100 miles !

Hydrogen nuclei undergo fusion within the Sun and this reaction releases energy as 0.3% of the hydrogen's mass is converted into energy. This energy spans several bands of the electromagnetic spectrum, most of it is in the UV-Vis portion. For more information look up blackbody radiation.

Radio Waves are in the lower end of the electromagnetic spectrum and have wavelengths between several hundred feet (AM Radio) to fractions of an inch (Microwave communications). X-Rays are high energy photons at the upper end of the electromagnetic spectrum, with wavelengths shorter than visible light, measured in nanometers to picometers. Color wise, Red is the longest visible, while Violet is the shortest wavelength of visible light. There are many graphical charts of the electromagnetic spectrum that show where the various waves fit in relation to each other, these can be found on an internet image search.
Several types of electromagnetic radiation from below the AM radio band up through the visible,
Stellar spectroscopes work by collecting radiation from an astronomical object. Studying the electromagnetic spectrum can allow you to work out its temperature, chemical composition and other characteristics.
No. Several other electromagnetic waves - including visible light - have a higher frequency.
Radio waves have the longest wavelength among the electromagnetic spectrum, ranging from several meters to kilometers in length.
According to NASA infrared radiation was first discovered in 1800, by a British astronomer named William Herschel. In an experiment to measure the difference in temperature between the colors in the visible spectrum, he placed thermometers in the path of light within each color of the visible spectrum. He observed an increase in temperature from blue to red, including an even warmer temperature measurement just beyond the red end of the visible spectrum.
