The frequency of a monochromatic light wave and its wavelength are related by the equation f = c/λ, where c is the speed of light in vacuum. Therefore, if the frequency of the wave is doubled, its wavelength must be halved in order to maintain a constant speed of light. This implies that option C (2f, λ/2) is correct, as it satisfies this condition. Option A is not correct, as doubling the frequency and wavelength would result in the same speed of light, which contradicts the definition of a monochromatic light wave. Option B is also not correct, as halving the frequency and wavelength would result in a lower speed of light. Finally, option D is incorrect, as we have already identified option C as a valid combination.
