Definition: A device that produces a bright light for a very short time, typically used in photography to illuminate a scene or subject.

Example: The photographer used a photoflash to capture the perfect moment in low light.

Definition: A type of electric lamp that gives off a strong, steady light, used mainly for photography.

Example: The photographer used a photoflood to ensure the subject was well-lit during the shoot.

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: 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.

Definition: The process in which an atom or molecule loses an electron after absorbing light, resulting in the formation of ions.

Example: Photoionization is an important process in astrophysics and atmospheric chemistry.

Definition: To cause an atom or molecule to lose an electron due to exposure to light or electromagnetic radiation.

Example: The intense light from the laser can photoionize the gas, creating charged particles.

Definition: Describing something that has been affected or created by the process of photoionization, where light energy causes atoms or molecules to lose electrons.

Example: The photoionized gas emitted a bright glow when exposed to ultraviolet light.

Definition: To cause an atom or molecule to lose an electron due to the absorption of light or electromagnetic radiation.

Example: The gas was photoionized by the intense ultraviolet light from the star.

Definition: Relating to a process that causes atoms or molecules to lose electrons due to the absorption of light.

Example: The photoionizing radiation from the star affects the surrounding gas clouds.
