It takes 186.67 seconds for the light to travel from Mars to earth.

What is Light?

Light is a visible form of energy that is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.

Formula

  • S = d/t .......................... Equation 1

making t the subject of the equation

  • t = d/S ......................... Equation 2

Where:

  • S = speed of light,
  • d = distance between the earth and Mars,
  • t = time

Given:

  • d = 56000000 km,
  • S = 300000 km per seconds.

Substituting these values into equation 2

  • t = 56000000/300000
  • t = 186.67 seconds.

Thus, it takes 186.67 seconds for the light to travel from Mars to earth.
