Answer:
0.657 seconds
Explanation:
speed of wave= wavelength / time period
so
time period= wavelength / speed
= 4.6/7
=0.657 sec
We use only one variable at a time to find the accurate result. We want to see how the result of experiment changes everytime with a single variable.
The answer is in the box
