Light is a form of EM radiation.
EM radiation has no mass (it's just energy packets called photons).
EM radiation can travel through a vacuum. (The speed of light in a vacuum is called c and is around 300,000 m/s).

I hope I helped you bye

Answer;

  • Light is a kind of electromagnetic radiation
  • Electromagnetic radiation has no mass
  • Electromagnetic radiation can travel through a vacuum.

Explanation;

  • Electromagnetic waves are those waves that do not require a material medium for transmission. These waves include; radio waves, x-rays, gamma rays, microwaves, etc.
  • These waves possess no mass, and despite having no mass they carry energy just like any other wave. They also travel at a velocity equivalent to the speed of light (3.0 × 10^8 m/s). Together these waves form electromagnetic spectrum which consists of electromagnetic waves arranged in the order of varying frequencies and wavelengths.
