Question

natural speed of light is _____​

Answer 1

• The speed of light in vacuum, typically abbreviated as c, is a universal physical constant that plays a role in a variety of physics fields.
• It has a precise value of 299792458 meters per second (about 300000 kilometers per second, or 186000 miles per second).
• It's precise because a meter is defined as the length of light's passage in vacuum during a time span of 1299792458 seconds by international agreement.
• According to special relativity, the speed at which ordinary matter, energy, or any signal containing information may move across space is limited by c.

Answer 2

Answer:

The natural speed of light is  $3$×$10^{8}m/s$ approximately.

Explanation:

Speed of light is defined as the speed at which light waves propagate through different materials. In a vacuum, the speed of light is measured as $299792458$ meters per second. We can take the approximate value as $3$×$10^{8}m/s$. It is a fundamental constant of nature. It is denoted by 'C'.
