Solve the following question given below:
Question: Two waves are superposing
y1 = (3 cm) sin [8.0/m x + 2.0/s t],
y2 = (3 cm) sin [8.0/m x - 2.0/s t]
Part A: What is the angular frequency?
Part B: Write down the equation for the resultant wave?
Could someone please show me the work and explain how to get the answer. Thanks.
