Answer

$\lambda = 1.06\times 10^{-5}~m$ $f = 2.83\times 10^{13}~Hz$

Work Step by Step

We can find the wavelength as: $\lambda = \frac{2L}{m}$ $\lambda = \frac{(2)(0.5300~m)}{100,000}$ $\lambda = 1.06\times 10^{-5}~m$ We can find the frequency as: $f = \frac{v}{\lambda}$ $f = \frac{3.0\times 10^8~m/s}{1.06\times 10^{-5}~m}$ $f = 2.83\times 10^{13}~Hz$
