Final answer:
The speed of light can be calculated using Maxwell's equations, specifically using the known values of permittivity and permeability of free space, which provides the speed of light as 1/√(ε0μ0) without the need for frequency.
Step-by-step explanation:
To find the speed of light without frequency, one should refer to Maxwell's equations. Specifically, the speed of light in a vacuum can be calculated using the known permittivity of free space (ε0) and permeability of free space (μ0) without requiring the frequency of the light. This is because Maxwell derived that the speed of light (c) is equal to 1/√(ε0μ0). Maxwell's equations show the relationship between electric and magnetic fields and how they propagate as electromagnetic waves at the speed of light. The basis for these calculations are found specifically in two of Maxwell's equations: the first being 'Faraday's law of induction' which relates a changing magnetic field to an induced electric field, and the second being 'Ampère's circuital law' with Maxwell's addition which relates a changing electric field to an induced magnetic field.
