to allow the vertebral artery to pass through to the brain
Well, darling, opaque substances are basically the divas of the material world - they don't let any light pass through them. Think of them as the ultimate light blockers, giving off major "don't bother me, I'm not in the mood" vibes. So, if you're looking for something that's as transparent as a politician's promise, opaque substances are the way to go.
Ultrapure quartz is one material that passes both the 254nm and 185nm frequencies of UV light developed by a mercury plasma tube, which itself is constructed using ultrapure quartz. If the quartz is not very pure, not much of the 184 nm frequency will get through. I think there are certain Teflons that will also pass UV light.
It reflects off of the object, and this is the light we see when we view opaque objects; it can be absorbedby the object, and we do not see this light; or the light can pass through the object in such a way that we can clearly 'see through' the object, such as transparent glass, or light can pass through the object and only appear as a glow, not an image, as is the case with some types of translucent plastic, frosted glass or other kinds of material.
It gets heated up and glows spreading the light
They allow different frequencies of light to pass through.
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
Opaque objects don't allow light to pass through. Pale is the abscence of colour.
Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.
These terms refer to the ability of a material to allow light to pass through it. Transparent materials allow light to pass through clearly, translucent materials allow some light to pass through but not clearly, and opaque materials do not allow any light to pass through.
Opaque materials do not allow light to pass through them.
transparent surfaces, allow light to pass through, translucent surfaces allow SOME light to pass through and opaque surfaces DO NOT allow any light to pass through
No, solid objects do not allow light to pass through them because the particles are tightly packed and do not allow for the transmission of light. Materials such as glass and plastic are transparent solids that allow light to pass through due to their molecular structure and arrangement.
The light on the wall will likely be green, as the green plastic will filter out light of other colors and only allow green light to pass through.
An opaque substance does not allow light to pass through it. Examples include wood, metal, and thick plastics.
I believe they are called "Noir" sunglasses. They allow only certain kinds light to pass thorugh because of some blind people's senstive eyes.
