the color of the hottest star is blue
The gravitational pressure and heat created by gravity causes nuclear fusion to occur in the core of the star. This energy flows through the star to its exterior, where it is radiated into space.
The Sun emits radiation in all parts of the Electromagnetic Spectrum. However, the strongest intensity radiation is at wavelength of around 450 nanometers. This is in the visible region.
No, the sun gives light to the moon, but not the stars. the stars give their own light.
noi it isnt it does not give off light.
Atoms give off (emit) electromagnetic waves by electrons dropping to lower orbit levels from higher levels of orbit.
to stay away from them. They give you cancer.

Mainly light and other electromagnetic wave.
No. There is a wide range of electromagnetic waves; we can only see a small amount. Depending on their frequency, electromagnetic waves are called radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x-rays, or gamma rays.
Radiation is energy transfer by electromagnetic waves.
You're free to give it any name that appeals to you. It's most commonly called the "electromagnetic spectrum" by others.
Radio waves and Light. Audio waves are not considered transverse. Since pressure is a constant, it eliminates a vector, thus making it a longitudinal wave.
X-ray part
Actually, there's only one. Even though we like to give different labels to electromagnetic waves with different wavelengths according to their uses or effects, they're all the same physical phenomenon.
pulsar
"Radio" is the generic name we give to electromagnetic radiation with frequencies less than 300 GHz (wavelengths greater than 1 millimeter).
