The EM Spectrum and Light!!



The EM Spectrum is the range of all the possible frequencies from electromagnetic radiation but if it's the EM of a particular object than it depends on how much electromagnetic radiation is distributed from as well as absorbed by the object,octaves are the product when EM radiation is divided.

Sound waves for example are approximately about 81 octaves.

The Speed of Light is approximately 299 792 458 m/s and one photon travels at that exact speed through a vacuum of space, one simple yet famous way used to measure the speed is Albert Einstein's theory of relativity which in short, explains that the measured speed of light is always the same whether or not the source of the light and the person doing the measuring are moving relative to each other.

Light or Visible Light is EM (electromagnetic) radiation of which is visible to the human eye as well as responsible for the sense of sight, visible Light has a wavelength of 380 nanometres to approximately 740 nanometres and a frequency range of about 405 THz to 790 THz (TetraHertz).

The colours that We can see are: red, orange, yellow, green, blue and violet
