Final answer:
The amplitude of the given wave is negative one-fifth, and the period is 2*pi.
Step-by-step explanation:
The amplitude of the given wave is negative one-fifth, as indicated in the equation y = -1/5 sin x. The negative sign indicates that the wave starts from its lowest point and extends upwards. The amplitude, which determines the maximum height or depth of the wave, is one-fifth of the y-coordinate.
On the other hand, the period of the wave can be found by dividing the full range of the x-coordinate, which is 2*pi, by the coefficient of x in the equation. In this case, the period is given by 2*pi divided by 1, which is 2*pi.
