Light sensitive materials contain molecules that undergo a chemical change when exposed to light. This change triggers a chain reaction that alters the properties of the material, such as color or conductivity. By controlling the composition and structure of these materials, we can create devices like photovoltaic cells or photochromic lenses.

What is the purpose of the cobalt blue glass?
The purpose of cobalt blue glass is to filter out ultraviolet and infrared light while allowing visible light to pass through, making it ideal for protecting sensitive materials from light damage or for decorative purposes.
What is the purpose of using cobalt blue glass in certain products or applications?
Cobalt blue glass is used in certain products or applications to block out ultraviolet and infrared light, making it ideal for protecting sensitive materials or substances from degradation caused by light exposure.
What property of sliver bromide makes it useful in photography?
Silver bromide is light-sensitive, meaning it reacts to light by forming silver particles, which creates an image. This property allows it to be used in photography for capturing and developing photos.
Does silver nitrate is light sensitive?
Yes, silver nitrate is light sensitive. Exposure to light can cause silver nitrate to decompose and break down, which can affect its stability and potency. It should be stored in a cool, dark place to minimize degradation.
What is the difference between luminescent and fluorescent materials?
Luminescent materials emit light without needing an external light source, while fluorescent materials absorb light and then emit it back at a different wavelength.
What materials do you use to build a model?
light-sensitive material
Is calcium sensitive to light?
Calcium itself is not sensitive to light. However, some calcium compounds or calcium-containing materials, such as calcium hypochlorite, can be sensitive to light and may degrade upon exposure.
How do light sensitive plasters work?
men
Why red light is used in developing photographs?
Red light is used in developing photographs because it has the least effect on light-sensitive photographic materials, such as film or photo paper. This allows photographers to work in a darkroom without exposing their materials to white light, which would ruin the photos being developed.
What is non light sensitive systems?
Non light sensitive systems are devices or materials that are not affected by exposure to light. These systems can function normally even in the presence of light and do not rely on light for their operation. Examples include electronic devices, mechanical systems, and certain types of sensors.
What and how do light sensitive polymers work?
They are used in hospitals as stitches because they will desolve in light and there is no need for them to be taken out.
What is light sensitive paper and how does it work?
Light sensitive paper is a type of photographic paper that changes color when exposed to light. It contains light-sensitive chemicals that react to light by darkening in areas exposed to light, creating a visible image. This process is used in traditional darkroom photography to create prints from film negatives.
Why do you use a red light in a dark room to develop pictures?
Using a red light in a dark room is a common practice in photography because it has a long wavelength, which means it is less likely to affect light-sensitive materials like photographic film or paper. Red light allows photographers to see and work in a darkroom without risking prematurely exposing or ruining their photosensitive materials.
Are worms sensitive to light?
Yes, they are sensitive to light.
Why do photographers develop film in a darkroom?
Because all the materials you use to do it with are light-sensitive and have to be handled in the dark.
Are plants sensitive to light?
yes plants sensitive to light
Why do photographers work with low light with selenium?
Photographers choose to work with low light in selenium toning because selenium toning has the ability to enhance the tonal range of black and white photographs, making subtle details in shadows more visible and increasing overall image contrast. This can help achieve a more dramatic and visually appealing final print.
