A stationary wave is set up on a stretched wire of length LLL and diameter DDD. A second wire is made from the same material and is stretched with the same tension as the first wire. What length and diameter for the second wire would result in it having an identical first-harmonic frequency to the first wire?

Length: 2L2L2L, Diameter: 2D2D2D

Length: 2L2L2L, Diameter: D2\frac{D}{2}2D​

Length: LLL, Diameter: 2D2D2D

Length: L2\frac{L}{2}2L​, Diameter: 2D2D2D
