Answer 1

Answer:

The order of magnitude of S.I. unit of speed of light light is 8 .

Therefore , Speed of light =3×10^8

Hence , the order of magnitude of speed of light is 8 at the power of 10 .

Extra information:

▪︎The speed of light in vaccum is 2,99,987 (approx) km/hr .

▪︎Speed of light in water is 2,20,000 (approx) km/hr .

▪︎Speed of light at glass is 2,00,000 km/hr .

▪︎The speed of light is denoted as "c" .

▪︎The speed of light means that the protons or the waves of the light travels at very high speed .

▪︎The light will take only 1.13s (approx) to reach the moon.

▪︎And the light which came from the sun takes 8 mins (approx) to reach the earth .

▪︎The 1 light year means the distance travelled by the light in a year .
