Answer
1.14 x 10^-4 m
Work Step by Step
To find the distance electromagnetic radiation travels in 0.38 ps we have to convert the ps to seconds. a picosecond is 1 x 10^-12 seconds so therefore:
0.38 ps * (1s / 1 x 10^12s) = 3.8 x 10^-13 seconds
The speed of light is 3 x 10^8 m/s so we have:
(3.8 x 10^-13 ) * (3 x 10^ 8 m/s) = 1.14 x 10^-4 m
