- What makes a neutrino different than a photon? Why is it that astronomers of the mid-20th century only seemed to detect approximately 1/3 of the neutrinos from the Sun that they had expected to?arrow_forwardFor several hundred years, astronomers have kept track of the number of solar flares, or sunspots which occur on the surface of the sun. The number of sunspots counted varies periodically from a minimum of about 10 per year to a maximum of about 110 per year. Between the maximum that occurred in the years 1750 and 1948, there were 18 completed cycles. A.) What is the period of the sunspot cycle? B.) Assume that the number of sunspots varies sinusoidally with the year. Sketch a graph of two sun spot cycles, starting in 1948. C.)
