Definition of actinic in English:
actinic
adjective akˈtɪnɪkækˈtɪnɪk
technical (of light or lighting) able to cause photochemical reactions, as in photography, through having a significant short wavelength or ultraviolet component.
Example sentencesExamples
- These states were detected both by short actinic flashes and by the switching of the actinic illumination level between different stationary state values.
- Leaves were then illuminated with actinic light and saturating flashes of 0.7 s duration were applied every 1.5 min.
- This approach can be very cost-effective, since the cost of non-LED based actinic illumination is significantly lower than LED-based illumination.
- Following this, leaves were illuminated with actinic light until a steady-state photosynthetic rate was reached.
- Continuous actinic illumination was provided through the fourth port of the vessel from a Schott KL1500 light source.
Origin
Mid 19th century: from Greek aktis, aktin- 'ray' + -ic.
Rhymes
clinic, cynic, Finnic, Jacobinic, rabbinic
