Definition: To strengthen or reinforce something again, especially a structure or position that has already been fortified.

Example: The army decided to refortify the castle after the recent attacks.

Definition: To change the direction of light or other waves when they pass through a medium, causing them to bend.

Example: The lens can refract light to focus it on the retina.

Definition: The bending of light or sound waves when they pass from one material to another, causing a change in direction.

Example: The refraction of light through a prism creates a rainbow effect.

Definition: Describing something that bends light or other waves when they pass through it.

Example: The refractive properties of the lens help to focus the light.

Definition: In a way that involves the bending of light or other waves when they pass through different materials.

Example: The light travels refractively through the glass, creating beautiful patterns.

Definition: The ability of a material to bend light as it passes through it, which affects how we see objects through that material.

Example: The refractivity of the glass made the image appear distorted.

Definition: A tool used to measure how much light bends when it passes through a substance, which helps in identifying materials or determining their sugar content.

Example: The scientist used a refractometer to check the sugar levels in the fruit juice.

Definition: Related to the measurement of how light bends when it passes through different substances using a specific instrument.

Example: The refractometric analysis revealed the concentration of the solution.

Definition: The process of measuring how much light bends when it passes through different materials, which helps to determine their refractive index.

Example: Refractometry is commonly used in laboratories to analyze the purity of substances.

Definition: An optical instrument that uses lenses to bend light and form images, often used in telescopes.

Example: The astronomer used a refractor to observe distant stars and planets.
