Question

The volume of velocity of light is vacuum or free space is

Answer 1

Answer:

i think it is vaccuum.............

Answer 2

The volume of the velocity of light in a vacuum or free space is 3 × $10^8$ m/s.

• Light travels approximately 300,000 Km/s in a vacuum.
• This has a refractive index of 1.
• The speed of light decreases to 225,000 Km/s in water with a refractive index of 1.3
• The speed of light in glass is 200,000 Km/s with a refractive index of 1.5
• Light is a form of electromagnetic radiation it has a wavelength such that it can be viewed with naked eyes.
