Question

If the speed of light is 3.0 into 10 race to power 8 m second calculate the distance travelled by light in one year and express it in scientific notation

Answer 1

Step-by-step explanation:

Speed of light = 3 × 10^8  m/s

Total No. Of Days in a year = 365

No. Of Seconds in a Day =  86400

∴ No. Of Seconds in a year  =  86400 × 365  =  31536000 seconds

[ Distance = Speed × Time ]

∴ Distance traveled by Light =  3 × 10^8 × 31536000

=  9.4 × 10^15  meters  =  9.4 × 10^12 Kilometer

Scientific Notation :-  9.4 × 10^12 Km  =  1 Light Year.

The Distance the Light travels in 1 Year is known as a Light Year.
