No, actually sodium vapor lamp is not monochromatic Approximately it can be said that the light has a wavelength of 589.3nm but actually it is composed of two wavelengths of 589.0nm and 589.6nm. Glass Cool White Sodium Vapour Lamps, for Outdoor, 35w Rs 1,450/ Piece Get Latest Price The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. (c = 3.0 x 10^8 m/s) a. A monochromatic lamp emits an 100.0 W beam of light that has a wavelength of 650 nm. This low color rendering index essentially means that it is very difficult to differentiate between the different colors of objects illuminated by this lamp. Since these lamps produce light at only one wavelength in the But afterward, some improvements made this lamp with 50000 initial lumens with 24000 hours at 10 hours per start. Assume that 60% of the consumed energy is converted into light. High-pressure sodium lamps render colors poorly, which tends to limit their use to outdoor and industrial applications where high efficacy and long life are priorities. 1.19 Sodium vapor lamps, used for public lighting, emit yellow light of wavelength 589 nm. Answer: c Explanation: A spectrum is observed, when light coming directly from a source is examined with a spectroscope. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
