A photomultiplier.
When sunlight reaches an object, it is either absorbed, reflected, or transmitted through the object. In the case of a tree, some sunlight is absorbed by the leaves and branches while the rest is blocked, creating a shadow behind the tree. Light does not bend around the tree because the tree acts as a barrier, preventing the passage of light to the area behind it.
A tree creates a shadow because it blocks the path of sunlight, preventing the light from reaching the ground in those areas. The shadow is formed as a result of the tree absorbing or reflecting the sunlight, causing darkness in the areas behind it where the light cannot reach.
The tree blocks the sunlight, preventing it from reaching the area behind the tree, creating a shadow. Light travels in straight lines, and when an object obstructs its path, it cannot pass through. This causes the area behind the tree to receive less light, creating the shadow.
An object can accelerate with changing speed by experiencing a change in velocity. This change can occur due to a net force acting on the object, causing it to speed up or slow down. Acceleration is a measure of how quickly an object's velocity is changing over time.
The property exhibited is reflection of light. The sunlight reflects off the tree and into the person's eyes, allowing them to see the tree.
A light meter is commonly used to measure the amount of light under a tree. It measures the intensity of light in lux or foot-candles, giving a numerical value that indicates the level of illumination in that area.
a clinometer is used to measure the height of an object such as a tree

A tree's shadow does not have light. Anytime you are in the shadow of another object your body has no shadow of its own.
A tree creates a shadow because it blocks the path of sunlight, preventing the light from reaching the ground in those areas. The shadow is formed as a result of the tree absorbing or reflecting the sunlight, causing darkness in the areas behind it where the light cannot reach.
The tree blocks the sunlight, preventing it from reaching the area behind the tree, creating a shadow. Light travels in straight lines, and when an object obstructs its path, it cannot pass through. This causes the area behind the tree to receive less light, creating the shadow.
To measure the height of a tree accurately, you can use a clinometer to measure the angle from your eye level to the top of the tree, then measure the distance from the tree to where you are standing. By using trigonometry, you can calculate the height of the tree.
The superstitions are taught to us for our safety/precautionary measure.
Light from the sun (or any other source) travels in particles, which strike objects and are often partially absorbed. A shadow forms behind a tree because when the particles hit the tree, they are absorbed and reflected, so that everything on the other side of the tree, where the light would have gone, receives no light. However, some light will bounce off of other objects and go behind the tree in the other particles' place. Since this other light will already have been partially absorbed, it will be more dim than direct light. Because of this, we are able to see in the shadow, but since the light there is not as strong, it is darker. This darker region behind the tree, is the shadow.

Sunlight shining through the canopy of a tree can cause a dappled effect of sunlight and shadow beneath the tree.
