When light travels from one substance to another, its speed and direction may change due to a change in the medium's optical density. This change causes the light to refract, or bend, as it passes through the interface between the two substances. The amount of bending is determined by the difference in the refractive indices of the two substances.
The ability of a substance to reflect light is known as reflectance. It is determined by the material's surface properties such as smoothness, color, and angle of incident light. A substance with high reflectance will appear bright and shiny, while a substance with low reflectance will appear dull.
In slang, "light" can mean to make something easier or less serious, or to reduce the intensity of a situation. It can also refer to someone who is not very serious or who lacks depth or substance.
When sound energy meets a new substance, three things can happen: reflection (bouncing off the substance), absorption (being absorbed by the substance and converted into another form of energy), or transmission (passing through the substance). The extent to which each of these occur depends on the properties of the substance and the frequency of the sound wave.
If one substance is known to be a better conductor of heat than another, it means that it can transfer heat more easily and quickly through its structure. This is typically due to the substance's arrangement of atoms and electrons, which allows heat to flow more efficiently compared to the other substance.
A light ray is a narrow, straight path that light travels in. A light beam is a collection of light rays traveling together in the same direction. Think of light rays as individual components that make up a light beam.
Chemical change
I suppose that you think to a reactant.
Chlorophyll.
The substance (usually a liquid) that can dissolve another substance is called a solvent.The substance that is being dissolved in a solution is called the solute.
A chemical change is when some thing changes into another energy or substance. It is important to make different things. A example is a piece of wood burning offers heat and light.
In any substance, all electromagnetic waves travel at the same speed that light travels through that substance.
transferring a virus to another person by means of a sneeze
it is something that has to do with metabolism but maybe you can search it up or ask someone!

Photosynthesis is the process that uses light energy to make new substances that have chemical energy.
