bonufazy [111]

The time taken by light to reach pluto will be 5.6 hours.

<h3><u>Explanation</u>:</h3>

The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.

The speed of light was calculated to be $3\times10^{8$ m/s. This is the speed of each and every electromagnetic waves.

The distance of pluto from sun is huge. On an average it's $6.1\times10^{9$ km or $6.1\times10^{12$ m.

So time taken by light to reach from sun to pluto will be $2 \times 10^4$ seconds. Or actually 5.6 hours.
