Wave Properties - A simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude.

A string of length $1.5 \mathrm{m}$ with its two ends clamped is vibrating in the fundamental mode. The amplitude at the centre of the string is $4 \mathrm{mm}$. The minimum distance between the two points having amplitude of $2 \mathrm{mm}$ is:

One end of a uniform string is attached to an oscillator which is oscillating along $y$ axis according to the law $y=\left\{\begin{array}{cc}t-\left[t\right]& 2n<t<2n+1\\ 0& 2n+1<t<2n+2\end{array}\right.$
Where $y$ is in meters, $t$ is in seconds and $n=0,1,2,3\dots .$ Other end of string is fixed to rigid wall. Tension in the string is $25 \mathrm{N}$, mass of string is $10 \mathrm{kg}$ and length is $10 \mathrm{m}$ Let oscillator be placed at origin and wall is at $x=10$ then answer following question. {Assume gravity free space and no damping}
