Problem
The following measured values of the fundamental constants are reported:
μ0=4π×10−7Hm−1 with an uncertainty of ±0.5%, and ε0=8.854×10−12Fm−1 with an uncertainty of ±0.2%.
(a) Calculate the numerical value of the speed of electromagnetic waves in vacuum using these data.
(b) Determine the percentage uncertainty in the calculated speed.
(c) The accepted value of the speed of light is 3.00×108ms−1. Does your calculated value agree with the accepted value within the stated uncertainty? State Yes or No with one-line justification.
