Solution

Step 1: Speed of light

  1. The speed at which light propagate is called speed of light.
  2. Speed of light is fundamental natural constant. It remain same everywhere.
  3. It is denoted by c.
  4. The formula to calculate speed of light is c=f×λ, where c= speed of light, λ = wavelength of light, f= frequency of light.

Step 2 : Speed of light in vacuum

  1. The speed of light in vacuum is 2.997×108m/s~3×108m/s.
  2. The speed of light is maximum in the vacuum.
  3. SI unit of speed of light is m/s.
