Explanation Reason for correct answer: Option c. is given as, “a vacuum”. The light travel faster in a vacuum as there is no particle to slow down the speed of light by the action of diffraction and refraction. Hence, option c. is correct. Reason for incorrect answer: Option a. is given as, “warmer air”. The speed of light is more is warmer air than cool air because the particles have more speed at higher temperature but the speed in less than the speed in vacuum because the speed of light decrease with the diffraction and refraction...
