Relative refractive index (n) is the ratio of the speed of light in a vacuum relative to that in a given material or medium. It is a measure of how much a material or medium slows down light when it passes through it. It is also known as the refractive index of the material or …
The law of refraction states that when a ray of light passes from one medium to another, the ray of light bends at the boundary between the two media. The angle of refraction is dependent on the indices of refraction of the two media and is described by Snell’s law.
Refraction of light is the bending of light as it passes from one medium to another, such as from air to water or from glass to air. This phenomenon occurs because the speed of light changes as it passes from one medium to another. The change in speed causes the light to bend, or refract. …
Optical density is a measure of how much light is absorbed by a material, usually a liquid or solid. It is calculated by measuring the intensity of light that passes through the material and is often expressed as a percentage of the incident light. Optical density is used to determine the concentration of a solution, …
Cartesian sign convection is a way of expressing symbolic equations in a two-dimensional form. It is based on the Cartesian coordinate system and uses positive and negative signs to identify the direction and magnitude of a variable. The sign convection is used to represent equations in a more convenient and visual way, allowing for easier …

Plane Mirror: A flat mirror with a smooth, polished surface that reflects light in a straightforward manner. Plane mirrors are often used as bathroom or dressing room mirrors, as they provide an accurate reflection of the person standing in front of them. Concave Mirror: A curved mirror that has an inward bulge, making the reflected …

Multi reflection light is a type of light that is reflected multiple times from surfaces within a confined space. This is often used to create special lighting effects and can be found in theatres and film sets.
Irregular reflection light is light that is reflected off of an uneven, unpredictable surface. This type of reflection occurs when the surface of the material is not flat or regular, such as a rough stone or a rough wall. The reflection is caused by the irregular arrangement of the material’s surface molecules, which results in …
Regular reflection light is light that is reflected off of a surface in an even, predictable pattern. This type of reflection is caused by the flat, regular surface of a material such as a mirror, a glossy paint, or a smooth, polished stone. The reflection is caused by the regular arrangement of the material’s surface …
Immediately turn off the power source. Check for breathing and pulse, and begin CPR if needed. If the person is conscious, reassure them and keep them still. If the person has stopped breathing, begin rescue breathing. Apply a cold compress to the affected area to reduce swelling. Seek medical help immediately.
