Definition: In a way that relates to the chemical reactions caused by light.

Example: The plants grow photochemically, using sunlight to convert carbon dioxide into oxygen.

Definition: A scientist who studies the chemical effects of light and how it interacts with different substances.

Example: The photochemist conducted experiments to understand how sunlight affects plant growth.

Definition: A branch of science that studies how light affects chemical reactions and processes.

Example: Photochemistry plays a crucial role in understanding how plants convert sunlight into energy during photosynthesis.

Definition: Relating to a substance that can change color when exposed to light.

Example: The photochromic lenses in my glasses darken when I go outside.

Definition: The ability of a material to change its color or transparency when exposed to light, especially sunlight, and then return to its original state when the light is removed.

Example: Photochromism allows sunglasses to darken in bright sunlight and become clear indoors.

Definition: To prepare written material for printing using a photographic process.

Example: The designer decided to photocompose the text for the magazine layout.

Definition: A device that senses and measures light or other forms of electromagnetic radiation.

Example: The photodetector is essential for capturing images in digital cameras.

Definition: A small electronic device that converts light into electrical current, often used in sensors and optical applications.

Example: The photodiode is used in the camera to detect light and help capture images.

Definition: To break down a molecule into smaller parts using light energy.

Example: The chemical reaction will photodissociate the compound when exposed to ultraviolet light.

Definition: Relating to the use of light to enhance effects or induce reactions, particularly in medical treatments like destroying cancer cells with light-sensitive dyes.

Example: The photodynamic therapy used in her treatment helped to target the cancer cells effectively.
