Lead is most often used as an insulation for X-rays. It blocks X-rays. That is what is inside those blankets dentists put over you when they X-ray your teeth.
radiolucent allows x-ray pass through radiopaque does not allow it to pass through
Rubber.
a non-conductor
Yes.
Insulator is a substance that does not allow heat to pass through it example air. conductor is a substance that allows heat to pass through it example metal.
An impermeable layer is a layer which doesn't allow any substance to pass through it.
It i scalled insulator. The substance do not allow heat to pass through it It Is also heat resistant (dont let heat through it). An example of a heat resistant material is wood.
transparent allow light to pass through and can see clearly through them and opaque has none of this ability
Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present. Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present.
Opaque materials do not allow light to pass through them.
They reflect or absorb light and thus do not allow light to pass through.
insulators do not allow electricity to pass through them whereas conductors allow electricity to pass through them.
