The summe â¦ r solstice, or June 21, is when we have the most amount of sunlight on a day in the whole entire year so therefore; maximum duration of insolation is greatest on that day. 1 person found this useful.

Lesson 44: Frequency, Wavelength, & Amplitude. The period means that it will take 4.5 seconds for the pendulum to swing back and forth once. So, I expect that my frequency will be a decimal, since it will complete a fraction of a swing per second. Be careful when changing the 700nm into metres.ince frequency and period are exact inverses of each other, there is a very basic pair of formulas you can use to calculate one if you know the otherâ¦. It is very easy to do these calculations on calculators using the x -1 button. Example 1: The period of a pendulum is 4.5s.
