What is the strength of area falling on a certain area
Light is measured in units called lux (luminous flux per unit area) or lumens (total amount of light emitted by a source). Lux is commonly used to measure the intensity of light falling on a surface, while lumens are used to measure the total output of light from a source.
It is called a shadow. When an object blocks the path of light, it creates a shadow on the surface behind it due to the absence of light in that particular area.
The area beyond the color violet in the visible light spectrum is called ultraviolet light. Ultraviolet light has shorter wavelengths and higher frequencies than visible light, and is invisible to the human eye.
A shadow is a dark area created when an object blocks light from reaching a surface. Shadows are formed when an object obstructs the path of light, causing a shadow to appear on the opposite side of the light source.

it is called an mandorla
The lighter-colored regions of the moon are called Highlands
It is called a black hole.
A complete area of shadow is called an umbra. It is the darkest part of a shadow where no light reaches.
The area beyond the color violet in the visible light spectrum is called ultraviolet light. Ultraviolet light has shorter wavelengths and higher frequencies than visible light, and is invisible to the human eye.
Places where light does not fall are called shadows. Shadows are formed when an object blocks the path of light, preventing it from reaching a surface or area.
A wall light is typically called a sconce or wall sconce. It is a type of light fixture that is mounted on a wall and is used to provide light for a specific area or as a decorative element in a room.
That whitish crescent shaped area at the base of a finger nail is called the lunula.
