optical opacity การใช้

• These defects result in considerable variations of its properties, including the increase of electrical conductivity and optical opacity.
• In 1939 he demonstrated that the major source of optical opacity in the Sun's atmosphere is the H  " ion, and thus the main source of visible light for the Sun and stars.
• In this case, it is easier to use the optical opacity \ kappa and to consider the internal temperature T I directly; more precisely, one can consider the average temperature in the radiation zone.
