- hi please solve this question . Make this its important, i just need the answer , in depth answer not required.Sunspots vary in number as a function oftime, exhibiting an approximately 11-year cycle. Galileo made thefirst European observations of sunspots in 1610, and daily observations were begun in Zurich in 1749. At the present time we are wellinto the 24th observed cycle. What is the frequency of the sunspotcycle? Give your answer in HzHi. Pls explainn the solution step by step. Where the numbers came from
