Radiation is the answer.
Answer: If a door is perceived as a rectangle even after being viewed from different angles, it is likely because our brain is applying a cognitive concept known as "shape constancy." Shape constancy is a perceptual phenomenon where we tend to perceive an object's shape as being consistent and unchanged, even when viewed from different angles or under varying lighting conditions.
This phenomenon occurs because our brains are constantly processing the visual information we receive and attempting to make sense of it. When we encounter a door, our brain has a preconceived notion that a typical door is rectangular in shape. As a result, even when we see the door from an angle that might distort its appearance, our brain adjusts the perception to maintain the idea that it is a rectangle.
This concept of shape constancy is a part of how our brains simplify the complex visual information we receive from the environment. It helps us recognize objects more easily and efficiently, even when they are presented in different orientations or lighting conditions.
In reality, the door may not appear as a perfect rectangle when viewed from various angles, but our brain's tendency to maintain shape constancy can override these visual discrepancies, and we continue to perceive it as a rectangle. It's important to note that this phenomenon is not limited to doors; it applies to many objects in our everyday lives, helping us make sense of the world around us.
Perception of a door as a rectangle from different angles is due to the flexibility of our visual perception, allowing our brain to adjust based on various factors. This can be observed in experiments where subjects acclimate to visual distortions over time.
When we view a door from different angles, it may still appear as a rectangle due to the way our brains perceive visual information. Our brains automatically adjust our perception based on various factors like lighting conditions, distance, and movement. This flexibility in perception allows us to make sense of the world around us. For example, in an experiment where subjects wore prism glasses to invert their visual field, initially, they perceived objects differently, but after acclimation, their perception returned to normal.

The ability of an apple to change color when exposed to air represents an example of a chemical change.
A chemical change may be defined as a type of change of materials into another form or new materials with different properties, and one or more than one new substance is formed spontaneously.
The change of color of the apple into brown when it is exposed to air is a chemical change. When you observed the color of an apple is to be brown, you are producing a chemical change. This involves the rearrangement of atoms in one or more substances resulting in a change in their chemical properties or composition.
Therefore, the ability of an apple to change color when exposed to air represents an example of a chemical change.
