Which of the following(s) is/are properties of light?


  1. Light is a form of energy

  2. Light travels in a straight line

  3. Light can travel through vacuum

  4. All of the above


Solution

The correct options are
A

Light is a form of energy


C

Light can travel through vacuum


The light rays from the sun reach the earth and so we can say that light can travel through the vacuum because outer space is nothing but a vacuum. We feel the heat from the rays of the sun. Thus, we can say that it has heat energy. Also, as light forms shadow, we can say that it travels in a straight line. Light is much more faster than sound, as we know that the speed of sound in air is 343 m/s while that of light is near 3 lakh km/s.
