Is called Doppler Effect
Doppler effect.
The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.
That is called the frequency of the wave.That is called the frequency of the wave.That is called the frequency of the wave.That is called the frequency of the wave.
The black body equation describes this in detail, it is called Plank's law. All bodies emit electromagnetic radiation. The hotter the body the higher the average frequency. Refer to the links in the Related links for lots of detail.

The highest frequency electromagnetic waves are called gamma rays. The waves are emitted from nuclei .

When light is traveling away from a black hole, its wavelength becomes longer. This is called blue-shifting. If it's going in, the wavelength becomes shorter, which is called red-shifting.

The ration of a frequency to its total frequency is called relative frequency.
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
''Charged particles emitted by the sun'' into space is called solar wind.
