Question

wavelength of light​

Answer 1

Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).

Formula: c = f where: c = the speed of light = 300,000 km/s or 3.0 x 108 m/s. = the wavelength of light, usually measured in meters or Ångströms (1 Å = 10-10 m) f = the frequency at which light waves pass by, measured in units of per seconds (1/s).

Hope it helps.

Answer 2

$\huge\blue{Answer}$

400 to 700 nanometres

Visible light is known to have wavelengths in the range of 400 to 700 nanometres (nm), or 4.00 × 10-7 to 7.00 × 10-7 m, which is between infrared which has longer wavelengths and ultraviolet which has shorter wavelengths. The wavelength of visible light implies it has a frequency of roughly 430 to 750 terahertz (THz).
