Problem 1 (5 points). For the following wave function: $f(x, t) = 2.0e^{-i(4.2 \cdot 10^{10}x - 1.1 \cdot 10^{15}t)}$. Find the wavelength $\lambda$ and wave speed $c$. If this wave then enters a dielectric medium of refractive index $n = 1.41$, what is the new wavelength $\lambda$ and wave speed $c$? ($x$ is specified in units of meters, and $t$ in units of seconds)
