Opaque materials do not allow light to pass through them.
insulators do not allow electricity to pass through them whereas conductors allow electricity to pass through them.
Yes, microwaves will pass through plain glass.
A polaroid allows light to pass through it in only one plane. If both polaroids are aligned, they will allow light to pass through the same plane. Otherwise, each will allow light to pass through a different plane and the overall effect of the two polaroids is that it will not allow light to pass through them.
opaque
Loose or sandy soils allow water to percolate(pass) through them faster
the type of rock is called a rock that does not allow water to go through it
Shale
the soil that allows water to pass through very slowly is clay
A porous and permeable rock will allow water to pass through. Rocks layers that allow the flow of water may be described as an aquifer.
Wrong. Water will pass through paper but low voltage electrity will not. Electricity will pass through copper and other metals, but water will not. Water is a good conductor of electricity but so is steel and copper. However water will not pass through them unless they are in the form of tubing In the UK pipework (Gas and Water) in properties should be earthed to protect against electrocution.
A layer of rock or soil that does not allow water to pass through it .
A kitchen sieve will allow this.
Permeability/ hydraulic conductivity.
freely and allow water and other hydrophylic molecules to pass through into or out of the cell.
