Choose a parallel on which at noon on the day of the autumnal equinox the minimum angle of incidence

Choose a parallel on which at noon on the day of the autumnal equinox the minimum angle of incidence of the sun’s rays will be observed: a) 55 * N b) 55 * S c) 60 * N d) 50 * S

On the days of the equinox, the sun is at its zenith above the equator, which means. that the northern and southern hemispheres are illuminated in the same way. From here we conclude that the further the parallel is from the equator, the smaller the angle of incidence of the sun’s rays. Of the proposed options, the parallel is 60 * N lat. farthest from the equator, therefore, on this parallel, the minimum angle of incidence of the sun’s rays is observed.
Answer: 60 * N.
