Photosensitivity - Interpretation in Chemistry

Interpretation in Chemistry

Chemicals that are photosensitive may undergo chemical reactions when exposed to light. These chemicals, such as hydrogen peroxide and many prescription drugs, are stored in tinted or opaque containers until they are needed to prevent photodegradation. Devices that are photosensitive include the human retina and photographic film; their photosensitive materials undergo a chemical reaction when struck by light.

Typical substances that are photosensitive are alkali salts and silver halides.

Famous quotes containing the word chemistry:

    For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world.... I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: “I will understand this, too, I will understand everything.”
    Primo Levi (1919–1987)
