What is the period of a soundwave whose wavelength is 20.0 m? use values from the book and show all of your work.

Answer;

Period = 1/17 seconds

Explanation;Wavelength is related to period by the expression:

speed = wavelength / period

If we are given the speed, then we can easily calculate the period at the wavelength of 20 m.

Given the speed of sound wave as 340 m/s

Period = Wavelength/ speed

           = 20 m/340 m/s

           = 1/17 seconds

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;
