Question

Why our shadow will become short or long in different time of a day ?

Answer 1

Explanation:

The sun casts shadows which change dramatically through the day. The length of a shadow cast on the ground is proportional to the cotangent of the sun's elevation angle—its angle θ relative to the horizon. Near sunrise and sunset, when θ = 0° and cot(θ) = ∞, shadows can be extremely long. If the sun passes directly overhead, then θ = 90°, cot(θ) = 0, and shadows are cast directly underneath objects.

Such variations have long aided travellers during their travels, especially in barren regions such as the Arabian Desert.[

Answer 2

Answer:

because of light

Explanation:

it is because of light...if you're standing at a place in the morning, your shadow will be long enough to see and if you are standing at the same place in afternoon your shadow will be short. this is because when sun rises it is adjacent to our body hence our shadow is long and when the sun is at the top in the afternoon our shadow is short...this is all because of light
