Two waves are described by the wave functions
y1 (x, t) = 5 sin(2x – 10t) m,
y2 (x, t) = 10 cos(2x – 10t) m,
where x is in meters and t in seconds.
1. Show that the wave resulting from their superposition is also sinusoidalby writing the resulting wave function.
2. What is the amplitude and phase of the resulting wave?
