Definition: Describing something that has become sensitive to light, often as a result of a chemical process.

Example: The photosensitized material reacted strongly when exposed to sunlight.

Definition: To make a substance sensitive to light, often used in scientific or medical contexts.

Example: The researchers photosensitized the cells to study their reaction to light exposure.

Definition: A substance that becomes reactive when exposed to light, often used in chemical reactions to produce a desired effect.

Example: The researchers used a photosensitizer to enhance the efficiency of the solar cells.

Definition: Relating to a process that produces copies of documents using light and electrostatic charges, often associated with photocopying technology.

Example: The photostatic copies of the documents were clear and easy to read.

Definition: A biochemical system in chloroplasts that plays a key role in the process of converting light energy into chemical energy during photosynthesis.

Example: The photosystem is essential for plants to convert sunlight into energy.

Definition: Relating to the movement of organisms in response to light.

Example: Certain insects are phototactic, moving towards light sources.

Definition: The movement of a living thing towards or away from light.

Example: Many plants exhibit phototaxis by growing towards the sunlight.

Definition: A system that transmits images or documents over a distance using electrical signals, often associated with early forms of fax technology.

Example: The invention of phototelegraphy revolutionized communication by allowing documents to be sent quickly over long distances.

Definition: A type of electronic component that can detect light and convert it into an electrical signal.

Example: The phototransistor is commonly used in light sensors and optical communication devices.

Definition: A type of electron tube that has a photosensitive surface, which releases electrons when exposed to light.

Example: The scientist used a phototube to measure the intensity of the light in the experiment.

Definition: A machine or person that creates printed text by using photographic techniques to arrange letters and images.

Example: The phototypesetter produced high-quality text for the newspaper.
