Question

The speed of light is 1.86×10^5 miles per second.how many meters will light travel in 1.0 seconds

Answer 1

Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). ... The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.

Answer 2

Answer:
`3.0* 10^8m`

Step-by-step explanation:

Speed is defined as the distance travelled per unit time.

`speed=(distance)/(time)`

Units of speed are inter convertible:

Given : speed =
`1.86* 10^5miles/sec`

That is in 1 second , light travels =
`1.86* 10^5miles`

Converting miles to meters:

1 mile = 1609.34 m

`1.86* 10^5miles=(1609.34)/(1)* 1.86* 10^5=3.0* 10^8m`

Thus speed of light will be
`3.0* 10^8` meters.
