7.17m/s glad I could help
Acceleration= change in velocity/time; 5/2.8 , so a=1.785714286

Answer: C. T
Explanation:
Period is a unit of time; and in the context of waves or oscillations it is defined as <em>"the </em><u><em>time </em></u><em>elapsed between two equivalent points on the wave or oscillation".</em>

It is important to note Period (denoted by
) is one of the most important factors (along with the amplitude, frequency and velocity) to describe and characterize a wave.
In addition, Period has an inverse relation with the frequency
, this means that if we are given the frequency of a wave, we can inmediatly know its Period.
Light waves can be from any color, depends on what it is bouncing no or reflecting off of.
