Spectrophotometer
Definition: A spectrophotometer is a scientific instrument used to measure how much light a substance absorbs at different wavelengths (colors) of light. It helps scientists understand the properties of materials by analyzing how they interact with light.
Usage Instructions: - In a laboratory, a spectrophotometer is often used for experiments involving liquids, like solutions of chemicals. - To use it, you would place a sample in the device, which then shines light through it and measures how much light passes through and how much is absorbed.
Example: - "The scientist used a spectrophotometer to determine the concentration of a dye in the solution by measuring the light absorption at specific wavelengths."
Advanced Usage: - Spectrophotometers can be used in various fields, including chemistry, biology, and environmental science, to analyze substances, test water quality, and study the characteristics of materials.
Word Variants: - Spectrophotometry (noun): The study or practice of using a spectrophotometer. - Spectrophotometric (adjective): Relating to the measurement of light absorption using a spectrophotometer.
Different Meanings: - While "spectrophotometer" specifically refers to the instrument, "spectrophotometry" might refer more broadly to the field of study or the methods used in experiments involving light measurement.
Synonyms:There are no direct synonyms for "spectrophotometer," but related terms include: - Photometer: A general term for devices that measure light intensity. - Colorimeter: A device that measures the concentration of colored solutions by determining the amount of light absorbed.
Idioms and Phrasal Verbs: - There are no specific idioms or phrasal verbs related to "spectrophotometer," as it is a technical term primarily used in scientific contexts.
