197- If Planck's constant is $6.6\times10^{-34}\ \text{J}\cdot\text{s}$, what is the ratio in electron volt seconds? $\left(e = 1.6\times10^{-19}\ \text{C}\right)$
(1) $\dfrac{\lambda}{33}\times10^{15}$ (2) $\dfrac{33}{\lambda}\times10^{-15}$ (3) $\dfrac{33}{\lambda}\times10^{-15}$ (4) $\dfrac{\lambda}{33}\times10^{15}$
