As an object increases in speed, so does the amount of energy that it has, this energy is what we refer to as 'the increase in mass' (just remember, this is inertial mass). ... Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.

Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves. ϵ0 and μ0 are properties of the vacuum and are constants, so c will also be a constant.
