Silver bromide is kept in a brown bottle to protect it from light exposure. Light can cause silver bromide to degrade, affecting its sensitivity to light and ruining its performance as a light-sensitive material in photographic applications. The brown color of the bottle helps to block out damaging light rays and prevent this degradation from occurring.
When a substance is heated, the kinetic energy of its molecules increases, causing them to move faster and further apart. This results in an expansion of the substance's volume. Conversely, when a substance is cooled, the molecules slow down and move closer together, causing the substance to contract.
The refractive index of a substance is a measure of how much light bends when passing through that substance compared to the speed of light in a vacuum. It is a dimensionless quantity that determines the speed of light in that medium. The higher the refractive index, the slower light travels through the substance.
A substance that causes pollution is called a pollutant. Pollutants can be in the form of chemicals, gases, or particles that are harmful to the environment and human health.
The presence of hydrogen ions (H+) in a substance causes it to be acidic. In an aqueous solution, hydrogen ions are responsible for the characteristic sour taste and ability to react with bases.

When the virus that causes chickenpox reactivates, it causes shingles. Early symptoms of shingles include headache, sensitivity to light, and When the virus that causes chickenpox reactivates, it causes shingles. Early symptoms of shingles include headache, sensitivity to light, and
Migraines can come about for almost any reason. These include stress, light sensitivity, sound sensitivity, and hunger. They also can be caused by genetics.
Visual disturbances include night blindness and increased sensitivity to light and glare.
When a substance transmits no light, it means that the substance absorbs all the light that comes in contact with it, preventing it from passing through. This could be due to the substance's molecular structure or composition, which causes it to absorb all wavelengths of light rather than allowing them to pass through.
Light and sound sensitivity during Migraine is caused by the neurological processes of the attack. Increased pressure is not related to Migraine and in fact is another headache disorder called Intracranial Hypertension._____________________________________________Increased pressureBlood vessels are expandig and increasing intracranial pressure which affects certain cranial nerves which leads to pain and increased light/sound sensitivity.
using a variable resistor we can adjust the sensitivity of a light dependent resistor
Being exposed to something your allergic to can potentially cause you to be sick. Being sick is your body's way of slowing down your cognitive functions, so that it can focus on getting rid of the thing that is making you sick.Example: If you are allergic to peanuts, and you eat one, there is a high chance that you will be sick.
Silicon, with an index of 3.96, is the lowest I could find.
She was afraid of both darkness and light. Although, medically speaking, photophobia is not an actual phobia. It's sensitivity to light, as when light actually causes your eyes to hurt, causing a reflexive aversion to light and light sources.
A substance with a high index of refraction bends light more than a substance with a low index of refraction. It indicates that light travels more slowly in that substance compared to air or a vacuum. This property is used in optics for lenses and other optics applications.
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
