11. The emissivity of Vantablack and scalability support a wide range of applications. 12. The concept of emissivity is important in understanding the infrared emissions of objects. 13. Experimental and theoretical emissivity as a function of wavelength. 14. We use the following model for emissivity in " U ": 15. The fraction of brightness temperature to actual temperature is defined as the emissivity . 16. The emissivity describes the ability of an object to emit energy by radiation. 17. Materials with higher emissivity appear to be hotter. 18. The object's known temperature can then be measured using the standard emissivity . 19. This emissivity depends on factors such as temperature, emission angle, and wavelength. 20. THe only thing you may have overlooked here is the emissivity of the paints.
