What is a material that light cannot travel through?
light can travel through anything. Light here means electromagnetic radiation, not just visible light. Visible light cannot go through anything opaque, such as metal sheets. Other types of electromagnetic radiation, like X-rays, can pass through almost anything. If you want the name ofa material where no EM radiation can pass through, it's thick lead sheet.
What absorbs alpha radiation?
Pretty much anything will. A couple of sheets of paper would do it. Alpha radiation is big and bulky compared to other types of radiation. So it can't penetrate objects very far.
How does a thermos flask reduce heat loss by convection?
A vacuum between two glass sheets will greatly reduce heat loss through convection, and also through conduction. The fact that the glass is coated (to convert it to a mirror) also reduces the loss by radiation.
What materials can nuclear radiation travel through?
The heavier and denser the material the more radiation it absorbs. Alpha is stopped by thin sheets, in fact the skin stops it mostly so it does not penetrate the body. Beta and gamma are best stopped by lead or concrete. Neutrons are more penetrating, they need to be stopped by hydrogenous material. Concrete is effective but needs to be thick. Water itself is a good neutron shield, as are heavy plastics and waxes. So radiation can travel through light materials and gases (and a vacuum), with the proviso about neutrons as above.
Which form of radiation will be stopped by a thick layer of concrete or a thick layer of lead?
Gamma rays and X-rays will pass right through paper (which will stop alpha rays) and aluminum sheets (that will stop beta rays), but can be stopped by a thick layer of concrete, lead, or other substances having sufficient mass.
How many sheets of polythene would it take to make a stack 6 inches tall?
That would depend on how thick the polythene sheets were.
Is polythene opaque?
Sheets of polythene like meat wrappings are obviously transparent. Thicker ayers can be translucent and almost opaque.
Why does clear polythene increase the yield of lettuces?
Clear polythene sheets can be used as covers for lettuce in order to extend the growing season into colder months and increase yields. Heavy polythene can also be used as a greenhouse cover in order to grow lettuce in cold months and increase yields.

Sheets of thick polythene stretched over a framework of bamboo canes would work.

Which type of rock can most easily be split into thin sheets?
the metamorphic rock that is easily split is...A Mica, A Pumice and A Sulfur
A metal can be hammered into thin sheets because it is?
Gold
Which rock splits easily into thin sheets?
Shale and slate can be cleaved into thin sheets of rock.
How do you Remove chewing gum from sheets?
In order to remove chewing gum, start by freezing the sheets. THis can be done easily by putting them outside if it is winter where you are. The gum will then break off easily. Once you break the gum off, thaw the sheets, pretreat the remaining stain, and wash them as you normally would.

What is the properties of slate?
It's chief property is that it is (easily) split into thin sheets.
