what is the wavelength of the light when it was emitted from the galaxy when the universe was only about 4 billion years old?

Respuesta :

The exact wavelength of the light would depend on the type of light being emitted from the galaxy. However, it is likely that the light would have a wavelength in the range of ultraviolet (UV) to near-infrared (NIR).

What is wavelength?
A waveform signal that is propagated in space or along a wire has a wavelength, which is the separation between two identical points (adjacent crests) inside the adjacent cycles. This length is typically specified in wireless systems in metres (m), centimetres (cm), or millimetres (mm) (mm). The wavelength is more frequently specified throughout nanometers (nm), that are units of 10-9 m, as well as angstroms (), which are units of 10-10 m, for infrared (IR), visible light (UV), and gamma radiation ().

Frequency, which is defined as the quantity of wave cycles per second, and wavelength have an inverse relationship. The wavelength of a signal decreases with increasing frequency.
