In 1 second, light can travel 2.998 x 10^8 m. How many inches does light travel in 1 femtosecond (1 fs = 10^-15 s, 1 inch = 2.54 cm exactly)?

Question

This is conversion using given information. 

Answer 1

Step 1. Calculate the speed of light in inch/sec

 

V= (2.998 x 10⁸ x 100)/2.54 = 11803149606 inch/sec

 

Step 2. Calculate the travel distance pertinent to 1 femtosecond

 

D = Vt = 11803149606 * 10^(-15) = 1.18031E-05 inch

 

Hope this will answer your question.
