Light and gravitational waves are distinct phenomena with different characteristics. While it is true that both light and gravitational waves are associated with energy and can interact with matter, they arise from fundamentally different physical processes.
Light, or electromagnetic radiation, is composed of photons, which are elementary particles that carry energy and interact with charged particles. Electromagnetic waves are created by accelerating charged particles, such as electrons, and consist of oscillating electric and magnetic fields. They can propagate through a vacuum or a medium and exhibit properties such as interference and diffraction.
On the other hand, gravitational waves are ripples in the fabric of spacetime itself. They are generated by accelerated masses, particularly in extreme astrophysical events like the collision of black holes or the explosion of supernovae. Gravitational waves propagate as disturbances in the geometry of spacetime, causing space to stretch and compress as they pass through.
While both light and gravitational waves are associated with energy and can transmit information, they have different physical properties and behave differently. Light is an electromagnetic wave that interacts with charged particles, while gravitational waves are disturbances in the fabric of spacetime caused by the acceleration of massive objects. So, light is not considered a gravitational wave.
