If Light goes from flint glass into ethanol The angle of refraction in the ethanol is 27.6 What is the angle of incidence in the glass?
If light goes from flint glass into ethanol and the angle of refraction in the ethanol is 27.6, the angle of incidence in the glass is approximately 23.21. This calculation is based on refractive index of pure flint glass being 1.60 and refractive index of ethanol being 1.361.
How was selenium used in the past?
In the past, selenium was mainly used in the production of glass to remove color caused by impurities and to make glass more transparent. It was also employed in photographic paper to increase sensitivity to light. Additionally, selenium was used in early electronics as a rectifying agent in devices like rectifiers and photovoltaic cells.
What is the speed of light in light flint?
The refractive index of flint glass is 1.6, approx. This means that the speed of light in flint glass is 1/1.6 of its speed in vacuum. This makes it 187,380,000 metres per second.
What element can be used to tint glass?
Metal oxides such as cobalt oxide, selenium, and gold chloride can be used to tint glass. These elements are added to the glass during the manufacturing process to alter its color.
Does selenium help with cancer?
Selenium is a mineral that acts as an antioxidant in the body, which may help protect cells from damage that can lead to cancer. However, more research is needed to determine the role of selenium in cancer prevention and treatment. It is important to talk to a healthcare provider before using selenium supplements for cancer.
What is selenium in?
selenium is inside many foods ,soil, and glass
How do you make transparant glass?
By adding gold or copper and selenium compounds to melted glass.
What element is represented by the symbol Se?
Selenium is represented by the symbol Se on the periodic table. It is a nonmetal element with various industrial uses, including in electronics and glass manufacturing.
What are the different types of glass wares?
soft glass Hard glass crown glass flint glass glass ceramics etc

What is selenium wanted for?
Several selenium applications:- rubber vulcanizatuin- solar cells- red glass- alloying element in brass- foods supplements
What is a flint cullet?
Cullet is actually a variant of word collet. This refers to the ring of glass that was left on the blow pipe when a glass blower was finished with a piece. The glass blower usually broke the leftovers off the pipe with a small hammer. The pieces were called the collets and recycled in the next batch of glass. Nowadays cullet means most any scrap glass. Flint glass usually refers to glass with a high lead content. But lead is not used much in regular glass container production anymore. Most flint glass nowadays is made with Soda and Lime (EAPG). The term flint can be applied to most any hard clean glass for recycling. Plate glass etc. Hope this helps.
What element is used to make pink glass?
The element that is used to make pink glass is selenium. This element is also used to make glass that is red in coloring.

How do you tell that a rock is flint?
Flint is a common name for a form of sedimentary rock called chert, formed from microscopic siliceous (essentially quartz) skeletons of radiolarians. As such the hardness of chert is 7, which is slighly harder than glass and considerably harder than steel. If it will scratch glass it is likely to be flint. Flint is often mistaken for limestone or marble, which is much softer and will not scratch glass.
What is the hardness of flint?
Flint is a type of Quartz, and Quartz is a 7 on the Mohs Hardness Scale
What was the economic impact of selenium?
Several selenium applications are:- fabrication of red glass- additive for the electrolysis of manganese- minor additive to fertilizers- copper alloys-vulcanization- solar cellsetc.
