Action Spectrum
Definition: Refers to the range of wavelengths of electromagnetic radiation that are most effective in driving a particular physiological or biochemical process, especially in photosynthesis or vision.
Examples
- Noun: The action spectrum of chlorophyll shows that it is most effective in absorbing light in the blue and red regions of the spectrum.
- Noun: The action spectrum of a photoreceptor determines its sensitivity to different wavelengths of light.
- Noun: In vision, the action spectrum of cones differs from that of rods, allowing them to detect color more effectively.
- Noun: Scientists have conducted numerous experiments to measure the action spectrum of various biological processes.
- Noun: Understanding the action spectrum of a particular biochemical reaction can help optimize conditions for its catalysis.
- Noun: The action spectrum of a sunscreen determines its effectiveness in protecting the skin from specific wavelengths of UV radiation.
