they've speed is determined by the medium in which each drive it's. Since the medium has not changed in this problem, the wave speed must remain a constant V. Let's go. Let me now. The product off frequency and wavelength is the way of speed. Therefore, the Waveland must be reduced by half when the frequency is so. Therefore the Waveland must be reduced by half off the initial value when the frequency is doubled in order for the live in other for V, which is the way of speed to remain constant in the medium. So let me just reframe everything. So, babe, speak a defense on the media Mid Travers and here, since the medium has not changed. Therefore, wave speed is going to be constant now. For this to be constant, our f times lambda must be a constant. So this means that Landau will be inversely proportional to one over will be inversely proportional to frequency. So if frequency is doubled, lambda should be reduced by half. So if if goes to two f, this means that Landa must go toe wander by two and this condition this, uh, value. These values are necessary for the velocity for the wave speed to be constant. So the correct answer is going to be option
