Red stars are cooler and emit more red light, blue stars are hotter and emit more blue light, while white stars fall in between and emit a broader spectrum of light. This color variation is due to differences in the stars' temperatures and compositions.
The Sun emits radiation across almost the entire electromagnetic spectrum.
Our sun emits mostly visible and ultra-violet radiation
Stars emit various types of radiation, including visible light, ultraviolet radiation, and infrared radiation. They also emit X-rays and gamma rays. The type of radiation emitted depends on the temperature and composition of the star.
Yes, stars produce electromagnetic waves as a result of nuclear fusion reactions in their cores. The energy released during these reactions causes the stars to emit electromagnetic radiation across various wavelengths, including visible light, ultraviolet light, and X-rays.
Most of the light emitted by humans is in the infrared part of the electromagnetic spectrum.

Optical light
Stars don't have electromagnetic waves. They absorb them and release them. It is not a known fact because electromagnetism is only a theory for now. However, light that reach us from stars are said to be EM waves because visible light is theorized to be in the EM spectrum.
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.
Very low temperature molecular clouds emit most of their light in the far-infrared and submillimeter parts of the electromagnetic spectrum. This is due to the low temperatures causing the atoms and molecules in the clouds to emit radiation at longer wavelengths.
The sun emits a continuous spectrum, which includes all wavelengths of light across the electromagnetic spectrum. This spectrum results from the thermal radiation of the sun's surface.
It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. Light = Energy = Heat = Can make light?
Red stars are cooler and emit more red light, blue stars are hotter and emit more blue light, while white stars fall in between and emit a broader spectrum of light. This color variation is due to differences in the stars' temperatures and compositions.

Blue LEDs typically emit light in the range of 450-480 nanometers, while red LEDs emit light in the range of 620-750 nanometers. Different LED colors emit light at different wavelengths, with each color having a specific range within the electromagnetic spectrum.
