Shadows appear longest in the morning when the sun is low in the sky, causing light to strike the ground at an angle and stretch shadows out; at noon, when the sun is directly overhead, sunlight comes almost straight down, minimizing the angle and causing shadows to shrink and appear directly beneath the object, making them seem to disappear.

Why Shadows Disappear at Noon ☀️ | Hidden Light Physics本站添加:
Notice how long I look in the morning?
That's because the sun is low in the [music] sky.
As the sun moves higher, the angle of light changes and I start [music] shrinking.
At noon, the sunlight comes almost straight down, >> [music] >> so I don't stretch out anymore.
With almost no angle, there's very little space for me to appear on the ground.
I don't disappear.
I just hide right beneath you.
