Question

what is the speed of light in vaccum?​

Answer 1

Answer:

$\large\boxed{\sf{3\times{10}^{8}\;m{s}^{-1}}}$

Explanation:

Light is a source of energy which has the maximum speed in vaccum.

The speed of light is about 3 lakhs Km per second in vaccum.

It's the light due to which we are able to see all the object in this universe.

Light follows a straight line path to travel.

In ray optics, we study the phenomenon and definition related to light and it's properties.

Light also follows the wave nature properties.

Light has both particle and wave nature.

The distance between very distant bodies in this universe is measured in light year.

One light year is the distance which the ray of light takes to travel in one year.

A vacuum is a volume that encloses little or no matter. In other words, it is a region that has a gaseous pressure much lower than that of atmospheric pressure.

Intensity is the amount of energy a sound wave has per unit of time. Intensity is measured in decibels, represented by dB. Softest sound: 0 dB. Harmful to hearing ≥ 85 dB.
