The given function should be in the form of f(x±vt).
So, for travelling wave y should be linear function of x and tand should be finite and continuous for all values of t.
y=Asin(15x−2t)→ linear function in x and t.
Which of the following equations represents a travelling wave?

The time period of a simple harmonic oscillator is $T=2 \pi \sqrt{\frac{k}{m}}$. Measured value of mass $(m)$ of the object is 10 g with an accuracy of 10 mg and time for 50 oscillations of the spring is found to be 60 s using a watch of 2 s resolution. Percentage error in determination of spring constant $(k)$ is $\_\_\_\_$ \%.
