Question

the distance travelled by light in one year is​

Answer 1

Explanation:

9.46×10^15. metre

or 9.46×10^12 kilometre

Answer 2

Answer:

See , first the speed of light is approx 2,99,790 km/s .

So , to find the distance travelled by light in one hour multiply it with how much second are there in a year .

And to find how many seconds in 1 year multiply how much second in one day with 365 days .

So , in 1 day second = 3600s (second in an hour) × 24 = 86400s .

So , now we can find how many seconds are there in an year .

Second in a year :

$\sf:\implies{86400s\times365}$

$\sf:\implies{31536000s}$

So , 31536000 seconds are there in a year .

Now , we can find the distance travelled by the light in one year .

Distance travelled by light in an year :

$\sf:\implies{D=2,99,790km/hr\times31536000s}$

$\sf:\implies{D=9,454,177,440,000km}$

So , the distance travelled by the light in an year is 9,454,177,440,000 km .
