All waves have the same wavelength.
All waves may not be of same frequency because all waves are of different energy levels and energy depends on the frequency which is different.
Radio telescopes give us information about the birthplace of a star.
Radio telescope is an astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation emitted by extraterrestrial sources.
If the wavelength of a wave increases, its frequency also increases.
relation between frequency and wavelength is given as
so they are inversely related to each other and hence if wavelength is increased then frequency must have to decrease.
Visible light is a kind of electromagnetic wave.
All visible light is a part of electromagnetic waves.
All objects emit electromagnetic waves.
Due to thermal vibrations all objects radiate electromagnetic waves of different frequencies.
Visible light is a form of electromagnetic radiation. Visible light falls in the range of the EM spectrum between infrared and ultraviolet light. So I'd assume it is.
Hope it helped!
i was thinking more like reflects green light, just not sure
visible light is a kind of electromagnetic wave....
