What is selenium sulfide lotion for?
Can selenium sulfide be used in treatment for lice?
Does selenium have any effect with light?
Selenium does not directly interact with light. However, selenium is used in the production of photocells, which convert light energy into electrical energy. Selenium can also be used in some photovoltaic applications to generate electricity from sunlight.
What is the wavelength of selenium?
The wavelength of selenium typically refers to the wavelength of light emitted by selenium when it is excited. Selenium emits light in the red part of the spectrum with a wavelength around 600-700 nanometers. This characteristic makes selenium useful in applications like photocopiers and photovoltaic cells.
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 electrical property of selenium is used in photocopiers and laser printers?
The property of selenium used in photocopiers and laser printers is its photoconductivity. Selenium becomes more conductive when light is shone on it, allowing images to be formed and transferred onto paper in these devices.

Is anything that this selenium sulfide shampoo used for be contagious?
Selenium shampoo is used for infections involving the fungus called malassezia furfur which is the cause of seborrhoeic dermatitis or seborrhoeic eczema. This condition is characterised by itchy, greasy skin on the face especially around the eyes and sides of the nose. By using selenium on the skin it controls the rash in irritation.

How is Selenium used in every day life?
The chief commercial uses for selenium today are in glassmaking and in pigments. Selenium is a semiconductor and is used in photocells. Uses in electronics, once important, have been mostly supplanted by silicon semiconductor devices. Selenium continues to be used in a few types of DC power surge protectors and one type of fluorescent quantum dot.
What is Se4Br7?
Se4Br7 is the chemical formula for selenium tetrabromide. It is a compound composed of selenium and bromine atoms, with four selenium atoms and seven bromine atoms in each molecule. Selenium tetrabromide is a red-brown solid that is primarily used in chemical synthesis.
