A high temperature source such as the Sun emits radiation across a wide range of wavelengths, from ultraviolet to visible light to infrared. The peak wavelength of radiation emitted by a high temperature source is determined by its temperature according to Wien's displacement law.
The color of an object can indicate its temperature through a concept known as blackbody radiation. Objects emit light at different wavelengths depending on their temperature. Hotter objects emit shorter, bluer wavelengths, while cooler objects emit longer, redder wavelengths. This is why we often associate blue with high temperatures (like a blue flame) and red with lower temperatures.
Shorter wavelengths.
All bodies are subject to entropy, the constantly increasing disorder of the universe, all energy tends to thermal equilbirum thus, places of high energy/temperature/ pressure/ will radiate into places of lower energy/ temperature/ pressure. Also see wiki on blackbody radiation for more detail on that topic.
Long wavelengths are associated with low frequencies. Examples include radio waves and AM radio signals, which have wavelengths in the range of kilometers to meters.
Black color absorbs more heat because it absorbs all wavelengths of light, rather than reflecting some like other colors. This absorption leads to an increase in the internal energy of the object, which is perceived as heat. Black bodies also radiate heat more efficiently due to their high absorbance, making them appear to be better at emitting heat compared to lighter colors.

Astronomers know the temperature of the Sun's corona is high because they can observe the emission of extreme ultraviolet and X-ray radiation from the corona, which is only possible if the temperature exceeds millions of degrees Celsius. These observations are made using instruments such as spectrometers and telescopes designed for detecting these high-energy wavelengths.

The original source for diamonds is carbon. They are formed by reaction of the high temperature and pressure in the Earth's mantle on minerals containing carbon.

Monsignor Donovan Catholic High School's motto is 'To Radiate the Lord'.
The convection cells radiate heat.
A low-density, high-temperature gas cloud would emit a continuous spectrum. This spectrum shows a broad range of wavelengths without any distinct lines, characteristic of thermal radiation emitted by hot objects.
