Neco Model Questions Vol1 2017 Physics Question 47
Practice objective / multiple choice question 47 from the 2017 Neco Model Questions Vol1 Physics examination.
Two harmonic waves travel in the same direction along a stretched string. The first wave is \(y_{1}=0.5\sin\bigl[2\pi(5t-0.2x)\bigr]\ \text{m}\) and the second wave is \(y_{2}=0.3\sin\bigl[2\pi(5t-0.2x)+\frac{\pi}{4}\bigr]\ \text{m}\). Determine the resultant amplitude of the combined wave (in metres, to two decimal places).
