Answer

$\lambda_1 = 2\lambda_0$ $f_1 = f_0$

Work Step by Step

We can write an expression for the initial conditions; $\lambda_0 = \frac{v_0}{f_0}$ We know that the frequency does not change when a wave goes from one medium into a new medium. We can write an expression for the new conditions; $\lambda_1 = \frac{v_1}{f_1}$ $\lambda_1 = \frac{2v_0}{f_0}$ $\lambda_1 = 2\lambda_0$
