In the given wave equation, the angular frequency is given by F1F1F1S1F1F1F10 = 2πν, where ν is the frequency of the wave. The frequency of the wave can be obtained from the argument of the sine function as: 3 F1F1F1S1F1F1F10 10⁶ m^-1 x - F1F1F1S1F1F1F10t = 2πν Comparing the above equation with the given wave equation, we get: ν = (3 F1F1F1S1F1F1F10 10⁶ m^-1)/2π Substituting the given values, we get: ν = (3 × 10 × 10^6)/(2π) Hz The angular frequency can now be calculated as: F1F1F1S1F1F1F10 = 2πν = 3 × 10^7 rad/s Finally, we can calculate the value of F1F1F1S1F1F1F10 as: F1F1F1S1F1F1F10 = F1F1F1S1F1F1F10/(10 × 10^-3) = 9 × 10^14 rad/s Therefore, the answer is (D) 9 F1F1F1S1F1F1F10 10¹⁴ rad/s.
