Answer is Right!
Answer is Wrong!
The speed of light is maximum in vacuum.
In a vacuum, there are no particles to interact with the light, so it can travel at its fastest speed. In solids, liquids, and gases, the light interacts with the particles in the medium, which slows it down.
The speed of light in a vacuum is 299,792,458 meters per second. The speed of light in a solid is about 200,000,000 meters per second. The speed of light in a liquid is about 225,000,000 meters per second. The speed of light in a gas is about 250,000,000 meters per second.
The speed of light is a fundamental constant of nature. It is the same for all observers, regardless of their motion. The speed of light is also the fastest speed at which information can travel.
