A region without light is called darkness.
The UV region is called "ultraviolet" because it has shorter wavelengths and higher frequencies than visible light, which is perceived as violet in the spectrum. "Ultra" means beyond, so ultraviolet implies light that is beyond violet in terms of wavelength and frequency.
Transmitted light.
Places where light doesn't reach are called shadows. This occurs when an object blocks the path of light, preventing it from shining on a particular area. Shadow formation is a result of the absence of light in that specific region.
The word for something that gives out light without heat is "luminescent." The process is called luminescence, and the light produced is often referred to as "cold light."
Materials that transmit light without scattering are called transparent materials. These materials allow light to pass through them with little to no distortion, making them ideal for applications like windows and lenses.
A region of land that is without a water boundary is known as "landlocked." Some US states that are landlocked are: Colorado, Kansas, Montana, Nevada.
The penetration of light into a region of geometrical shadow is called "penumbra." This occurs when only partial obstruction of light causes a partial shadow to be cast.
The energy leaves the sun as light from the region called the photosphere. This is the visible surface of the sun where most of the sunlight we receive on Earth originates.
The lighter region of a shadow is called the penumbra, which is the area where some light can still reach.
Penumbra
The region of a shadow that is partially shaded is called the "penumbra." In this area, only a portion of the light source is obscured, resulting in a gradient of light and shadow. The penumbra contrasts with the "umbra," where the light source is completely blocked, creating a darker shadow.
A dry region without trees or water is called a desert. Plants and animals need special adaptations in order to survive in this harsh environment.
The UV region is called "ultraviolet" because it has shorter wavelengths and higher frequencies than visible light, which is perceived as violet in the spectrum. "Ultra" means beyond, so ultraviolet implies light that is beyond violet in terms of wavelength and frequency.
The phenomena of sending back of light is called reflection of light. And the surfaces which reflects light back are called reflecting surfaces.
