Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
Answer:
Acceleration is rate of change of velocity.
The equation of turtle's position as a function of time is given by:
Differentiate the above equation to find the velocity as a function of time:
Differentiating further, we would get the equation for acceleration:
Therefore, initial acceleration is
