Abstract

This article analysis the variation laws of the shadow length on each parameter, and obtain the shadow length curve of a known straight rod. The shadow length is directly related to solar altitude angle and the length of rod. The factors that affect solar altitude angle directly are: solar declination, geographical latitude, time angle. Among them, solar declination is determined by date, angle by the local time, and local time is related to latitude and time. According to the relationship between the three factors and the solar altitude angle, the change law of the solar altitude angle is obtained, and the variation curves of the parameters are deduced
