In one second light can travel 2.998x10^8m. How many inches does light travel in one femtosecond?
There are 39.37 inches in a meter.
There are 10^15 femtoseconds in a second.
Use dimensional analysis to set up the problem.
To find out how many inches light travels in one femtosecond, we need to convert the speed of light from meters per second to inches per second first.
1 meter is equal to 39.37 inches. Therefore, we can calculate:
2.998 x 10^8 m/s x 39.37 inches/m ≈ 1.1811 x 10^10 inches/s
Now, we can convert this value to inches per femtosecond by dividing it by 10^15, as there are 10^15 femtoseconds in a second:
1.1811 x 10^10 inches/s ÷ 10^15 ≈ 1.1811 x 10^(-5) inches/fs
So, light travels approximately 1.1811 x 10^(-5) inches in one femtosecond.
To calculate how many inches light travels in one femtosecond, we need to convert the given speed of light from meters to inches and then scale it down to a femtosecond.
First, let's convert the speed of light from meters to inches.
1 meter is approximately equal to 39.37 inches.
Therefore, to convert meters to inches, we multiply by 39.37.
So, the speed of light in inches per second is:
2.998 x 10^8 m/s * 39.37 in/m = 1.181 x 10^10 in/s
Next, let's calculate how many inches light travels in one femtosecond.
One femtosecond is equal to 10^-15 seconds.
So, to calculate the distance light travels in one femtosecond, we multiply the speed of light in inches per second by the number of femtoseconds:
1.181 x 10^10 in/s * (10^-15 s) = 1.181 x 10^-5 in
Therefore, light travels approximately 1.181 x 10^-5 inches in one femtosecond.
