3.00 X108 m/s
|
|
|
is constant
|

all answers are correct
|
Explanation:
Detailed explanation-1: -Hence, the speed of light in vacuum is 3 × 10 8 m / s .
Detailed explanation-2: -The speed of light in vacuum is 3×108 m/s. Sunlight takes about 8 minutes to reach the Earth.
Detailed explanation-3: -Light in a vacuum is generally held to travel at an absolute speed, but light traveling through any material can be slowed down. The amount that a material slows down light is called its refractive index. Light bends when coming into contact with particles, which results in a decrease in speed.
Detailed explanation-4: -Light travels with maximum speed in vacuum. Speed of light in vacuum is 3×108 m/s and is denoted by c.
