An electromagnetic wave is represented by the electric field $$\vec{E} = E_0\hat{n}\sin(\omega t + 6y - 8z)$$. Taking unit vectors in x, y and z directions to be $$\hat{i}, \hat{j}, \hat{k}$$, the direction of propagation $$\hat{s}$$, is:

A

$$\hat{s} = \frac{3\hat{i} - 4\hat{j}}{5}$$

B

$$\hat{s} = \frac{-3\hat{i} + 4\hat{j}}{5}$$

C

$$\hat{s} = \frac{4\hat{i} - 3\hat{k}}{5}$$

D

$$\hat{s} = \frac{-4\hat{i} - 3\hat{k}}{5}$$
