Suppose the amplitude of modulated wave equal to the signal amplitude. Then modulation is (A) $10 \%$ (B) $25 \%$ (C) $50 \%$ (D) $100 \%$
A sinusoidal wave is described by the wave function $y=$ 0.25 $\sin (0.30 x-40 t)$ where $x$ and $y$ are in meters and $t$ is in seconds. Determine for this wave (a) the amplitude, (b) the angular frequency, (c) the angular wave number, (d) the wavelength, (e) the wave speed, and (f) the direction of motion.
