Transparent means that you can see through it! But it might not be apsalutley clear!
In science, translucent describes a material that allows some light to pass through, but scatters it in different directions, making objects on the other side appear blurry or hazy. This is in contrast to transparent materials, which allow light to pass through with minimal scattering.
Transparent materials.
Semi-transparent refers to an object or material that allows some light to pass through but is not completely transparent, meaning it is partially see-through or opaque. This property is often used in design to create effects like soft lighting or layered visuals.
Transparent means that light passes through it, and therefore you can see through it. Examples are glass and water. Metaphorically, something transparent (e.g. a ruse, a scheme) is a disguised activity that is easily "seen through," i.e. apparent in its aims.
A lens is a curved piece of glass or transparent material that is designed to refract (bend) light rays, focusing them to create an image. Lenses are commonly used in cameras, eyeglasses, microscopes, and telescopes.
