Definition: Relating to properties that depend on the number of particles in a solution rather than the type of particles.

Example: The boiling point elevation is an example of a colligative property.

Definition: To adjust the direction of an optical device so that its line of sight is straight and parallel.

Example: The technician needed to collimate the telescope before the stargazing event.

Definition: Describing light beams that are parallel to each other, resulting in a flat wavefront.

Example: The laser emitted a collimated beam of light that traveled long distances without spreading out.

Definition: To align or focus light or other waves into a parallel beam.

Example: The laser beam was collimated to ensure it traveled straight over a long distance.

Definition: Describing something that aligns or focuses light or other waves in a parallel direction.

Example: The collimating lens helped to direct the laser beam accurately.

Definition: To adjust the parts of an optical system so that they are aligned properly, allowing for accurate focusing and imaging.

Example: The technician is collimating the telescope to ensure the images are sharp and clear.

Definition: The process of aligning lenses or mirrors so that light rays travel in parallel, reducing distortions in images.

Example: The technician performed collimation on the telescope to ensure clear images of distant stars.

Definition: Relating to events where two or more objects hit each other, especially in the context of particles or physical bodies.

Example: The collisional effects in the experiment were significant in understanding particle interactions.

Definition: To appear together with other words in a specific way, often forming a common phrase or expression.

Example: In English, the word 'make' often collocates with 'a decision'.

Definition: To place words or phrases together in a way that is commonly accepted in a language.

Example: In English, some phrases like 'make a decision' are common collocations.

Definition: Relating to the way words are often used together in a language.

Example: In English, certain adjectives are collocational with specific nouns, like 'strong coffee' instead of 'powerful coffee'.

Definition: Relating to a type of mixture where tiny particles are suspended in a liquid or gas, but do not settle out.

Example: Milk is a colloid because it contains tiny fat particles suspended in water.

Definition: A type of mixture where tiny particles are spread throughout a liquid or gas, but do not settle out or can be easily filtered.

Example: Milk is an example of a colloid because it contains tiny fat particles dispersed in water.
