We are going over constructive and descrtuctive interference . We are learning how to adjust waves but im getting confused how to do the math to draw the new wave. My teacher was saying to use the blocks then only using the yaxis values and do the math per section. but im completetly confused. Could you explain step by step the easiest way on how to solve it . I have pictures, i was able to solve one after several attempts but im still lost if is possible to go over both questions. Q1

The red and blue waves are interfering with each other as hown, what will be the resultant wave? Draw it on the graph clow. Pressure (atm) Time (8)\fThe red and blue waves are interfering with each other as shown, what will be the resultant wave? Draw it on the graph below. Pressure (kPa) Time (s)
