Exam: GRE (Verbal)

Definition: The process of releasing electrons from a material when it is exposed to light, particularly from metals.

Example: The experiment demonstrated the phenomenon of photoemission when the light hit the metal surface.

Definition: Relating to the process where light causes the emission of electrons from a material.

Example: The photoemissive properties of the material make it suitable for use in light sensors.

Definition: The process in which a substance's atoms or molecules become excited after absorbing light energy.

Example: Photoexcitation is essential in processes like photosynthesis, where plants convert light energy into chemical energy.

Definition: Describing an atom, molecule, or ion that has gained energy and become excited as a result of absorbing light.

Example: The photoexcited molecules reacted quickly with their surroundings.

Definition: To cause a substance to become excited or energized by light, typically in a scientific context.

Example: The molecules were photoexcited by the laser beam, leading to a reaction.

Definition: Relating to the study of geological features using photographs, especially aerial images.

Example: The photogeologic analysis revealed new insights into the landscape's formation.

Definition: The study of geological features and formations using aerial photographs.

Example: Photogeology helps scientists understand the Earth's surface and its geological history.

Definition: Relating to the technique of obtaining measurements from photographs, especially for creating maps or 3D models.

Example: The photogrammetric analysis of the landscape provided detailed information for the project.

Definition: The method of creating maps or drawings using photographs, particularly those taken from the air, to obtain accurate measurements.

Example: Photogrammetry is widely used in surveying and mapping to create detailed topographic maps.

Definition: Caused or activated by the action of light, especially in the context of electromagnetic radiation.

Example: The photoinduced reaction occurred when the light hit the chemical compound.

Definition: A process where light causes a change or effect in a material or system.

Example: The photoinduction process is essential in many biological and chemical reactions.
