How does the relation `c-frac(1)(sqrt(mu_0 epsilon_0)` indicate that the velocity of all types of e.m. waves in free space is the same?

What is the velocity of e.m. waves in free space?

Show that (E_0)/(B_0 sqrt(mu_0 epsilon_0)) = c^2

Check the correctness of the relation c = 1/(sqrt(mu_0epsilon_0)) dimensionally and numerically.

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:The ratio of the amplitudes of elctric and mgnetic fields is constant and it is equal to velocity of the electromagnetic waves in free space. Reason:It is because, B_0= c E_0 .

Two points are located at a distance of 10 m and 15 m from the source of oscillation .theperiod of oscillation is 0.05 sec and the velocity of the wave is 300 m s^(-1) .What is the phase difference between the oscillation of two points?
