Because they are always fully aware that the moment they allow any light
to pass through them, they will lose the coveted distinction of being known
as 'opaque', and will become relegated to the dregs of the translucent.
opaque objects
A material that will not allow the transmission of light is called an opaque material.
Opaque objects don't allow light to pass through them while translucent objects slow the passage of light but ultimately allow it to pass through.
Opaque objects don't allow light to pass through. Pale is the abscence of colour.
Be careful not to confuse: Opaque objects are those that do not allow light to pass through it, but they can reflect light. It is BLACK objects that absorb all the incident light on it. To conclude, opaque objects do not necessarily absorb all the incident light on them but black objects ABSORB all the incident light on them (and are, of course, opaque)
Any object that doesn't appear allow light to pass through it is opaque. This includes you and a lead vest.
Transparent objects are the sorts of objects that light passes through. Translucent objects allow the partial transmission of light. Opaque objects prevent the transmission of light.
Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.
OPAQUE is the word that describes an object or substance that blocks light (or other energy form). TRANSLUCENT describes objects that allow transmission of light, but scatter it from the original form or direction. TRANSPARENT describes objects that allow the passage of light, usually optically clear substances such as glass.
Why can't light pass through what? To first contributer, don't say that. Say light cannot pass through solid, opaque objects at times.
There are 3 types of objects:1.TRANSPARENT OBJECTS:(have no shadow)it is the object that you can see clearly through .EX: water , gas2.SEMI-TRANSPARENT OBJECTS:can be seen through but not clear enough.3.OPAQUE OBJECTS:(have a shadow as light cannot pass through it but reflects)can't be seen through at all.
Opaque objects do not let light to past through so it will not cause a shadow. Because light cannot get through an opaque object, it will cast a shadow on the side opposite of the light.
