Cosine law, английский
- A law of illumination which indicates that the flux radiated or received in a
- Physical law stating that the illumination of a surface varies as the cosine of the incidence angle. maximum illumination is obtained where the cosine equals one and when the source is perpendicular to the surface.
- In nondestructive testing, physical law stating that the illumination of a surface varies as the cosine of the incidence angle. maximum illumination is obtained where the cosine equals one and when the source is perpendicular to the surface. coulomb (c): si unit for electric charge, replaces faraday and ampere hour, where 1 a·h = 3600 c. x-ray or gamma ray intensity is measured in coulomb per kilogram (c·kg–1).
- See lambert’s cosine law.
