Nature of light

Light is transverse and electromagnetic radiation that exhibits the properties of a wave as well as a particle. For this reason, light is said to have a “dual nature.”

Question

Does the fact that the light flash from lightning reaches you before its sound prove that the speed of light is
extremely large or simply that it is greater than the speed of sound? Discuss how you could use this effect
to get an estimate of the speed of light.
