When two shadows come to be close enough, the “rough outline/shape” due to diffraction will attract together before two object touch each other in reality, this will cause the phenomenon you mentioned in your question.

Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!

The tilt of the Earth’s axis affects the length of our shadows. During the summer, our location is tilted towards the Sun, so our midday shadows are very short.

At noon the sun is directly overhead. So, the sun rays fall vertically on the body. Hence the shadow is very short. In the morning and evenings, the sun rays fall in an inclined position.

-At different times of the day, your shadow will be different because of the position of the sun. -Your shadow is small at noon because the sun is above you. In the morning and evening, your shadow will be tall. The light causes your shadow to change.

Under what circumstances? Answer: Yes,Because of the movement of the light and motion of the body. Every time you move The shadow changes because The direction Of the light Has only 1 Direction.

The size of the shadow depends on the size of the object, the distance from the light to the object and the distance from the light to the screen.

The shadows cast by objects on Earth change in length because the angle at which the Sun’s rays hit the object changes. Large angles – when the Sun is at the horizon – make long shadows.

Indoors, you can change the size of a shadow by moving your body or the object closer to or farther from the light. Shadows grow bigger and fuzzier as the object moves closer to the light source, and smaller and sharper as the object moves farther away.

Size: Shadows can change their size. As light moves towards the object, the shadow becomes larger. As light moves away from the object, the shadow becomes smaller. Shape: Shadows can also change their shape.

The sun is the star around which Earth moves in orbit. Since the sun’s position in the sky during the course of the day changes due to the rotation of Earth on its axis, the shapes of outdoor shadows also change during the course of the day. Shadows can change in length, shape, and position.

Yes, the shadows are shrinking giving less cover to hide under, but it feels hotter because the sun is barring straight down on you. The sun doesn’t change size or temperature during the seasons, only our position changes. The days get longer, our shadows get shorter, but the science stays the same.

The length of shadow to your height is proportional to 1/Tangent (sun’s altitude). If the sun is low in the sky (10 degrees), your shadow would be 5.67 times as long as your height. The corresponding ratio at 5 degrees is 11.43 . (So an average height person (5.8 feet) would have a 66 foot long shadow).

A lunar eclipse occurs when the Earth lines up directly between the sun and the moon, blocking the sun’s rays and casting a shadow on the moon. As the moon moves deeper and deeper into the Earth’s shadow, the moon changes color before your very eyes, turning from gray to an orange or deep shade of red.

we can only see shadow in presence of light only…. because when light falls on an object the shadow forms on opposite direction…

As the moon orbits the Earth, the amount that is in shadow changes constantly. There’s nothing physically covering it; the darkness is a result of your vantage point.

The Moon is outside the Earth’s magnetic field for most of each month and has a negligible atmosphere, allowing solar-wind particles to reach the Moon’s surface.
