In a pressure dependent system, two zones. on the same system are effected by the control of one. another. Example â. Room A and Room B are two conference rooms. Both. are supplied by different VAV terminal units from the. same central air supply.
The color of a star depends on its surface temperature. Our Sunâs surface temperature is about 6,000 Kelvin. Although it looks yellow from here on Earth, the light of the Sun would actually look very white from space. This white light coming off of the Sun is because its temperature is 6,000 Kelvin.
Light from Stars. Because stars emit light with different wavelengths, they have different colors. Stars do not just emit one wavelength of electromagnetic radiation, but a range of wavelengths. If you look at the amount of light a star gives off at different wavelengths, you would get a graph like the one shown to the right. The wavelength at which a star emits the most light is called the star's peak wavelength.
