In 1 second, light can travel 2.998 *10⁸ m. How many inches does light travel in 1 femtosecond (1 fs = 10^-¹⁵ s, 1 inch = 2.54 cm)?

Question

Quizplus · Accepted Answer

To find the distance light travels in 1 femtosecond, we need to multiply the speed of light in 1 second by 10^-15 (1 femtosecond = 10^-15 second).
(2.998 x 10^8 m/s) x (10^-15 s) = 2.998 x 10^-7 m
To convert this to inches, we need to multiply by the conversion factor:
(2.998 x 10^-7 m) x (39.37 in/m) = 1.18 x 10^-8 in
Therefore, the answer is D: 1.18 x 10^-8 in or 1.18 femtoinches.
