laser beam
Materials that allow light to pass through them are called transparent materials.
An object that does not allow light to pass through it is called opaque. Opaque objects absorb or reflect light, preventing it from transmitting through them.
The passage of light through an object is called transmission. This process occurs when light passes through a material without being absorbed or reflected.
An object that lets no light pass through is called opaque.
The hole in the center of the iris through which light can pass is called the pupil.
Laser Beam

Light beams are photon particles that can be radiated/emitted in a beam, or concentrated in a stream (also known as a LASER - Light amplification by stimulated emission of radiation.)
A powerful lamp is often referred to as a floodlight due to its ability to emit a strong and broad beam of light over a wide area. Floodlights are commonly used for outdoor lighting, security purposes, and in sports stadiums to illuminate large spaces effectively.
in bio we call triple beam is a scale!
An object through which light cannot pass is known as opaque.
Diffraction.
Materials that allow light to pass through them are called transparent materials.
Crepuscular rays
