Each vegetables and fruits will have different response to the varying temperature and atmospheric condition of the surrounding. Some may become rotten in a shorter period of time. In this regard the price would get lower in order for the goods to get sold easily.
Answer:
velocity = frequency * wavelength
Given the wavelength one must also have the frequency.
The planar simple harmonic wave travels in the positive direction of x axis with wave velocity u=2m/s, and the vibration curve of the particle at the origin in cosinusoidal form is shown in the figure.
Try to find (1) the vibration function of the particle at the origin, (2) the wave function of the planar simple harmonic wave according to the origin.
