Suppose you stand at the same spot during the morning and the afternoon. In the morning, your shadow points in one direction, while in the afternoon it points in another. Why? Would the length of your shadow be the same at both times?
The shadow points in different directions in the morning and afternoon because the Sun appears to move from East to West during the day. In the morning, the Sun is in the East, so shadows point towards the West. In the afternoon, the Sun moves towards the West, so shadows point towards the East. The length of the shadow would not be the same at both times. Morning shadows are long, noon shadows are short, and evening shadows are long again. So, the morning shadow would be longer than the afternoon shadow depending on the time.
Explanation
The chapter explains on page 4 that 'Shadows at morning are long, noon shadows are short and shadows at evening are long again. However, the evening shadows appear in the opposite direction of morning shadows.' On page 6, it further states: 'The Sun appears to move from the East to overhead till noon and then, gradually moves towards the West in the afternoon. The direction of the shadow also changes because of the movement of the Sun.'
