Homework Equations
The Attempt at a Solution
Yes - electrons move between fixed energy levels in the atom and need a fixed amount of energy to do this. This corresponds to a photon of a particular wavelength.i understand that the wavelength given off by a sodium vapor lamp is 589nm, is this why there is a dark line in the continuous spectrum at 589mn?
A sodium vapor lamp is a type of high-pressure gas discharge lamp that produces light by passing an electric current through ionized sodium vapor. It is commonly used for street lighting and other outdoor applications.
A sodium vapor lamp works by passing an electric current through a sealed tube filled with sodium vapor. The electric current excites the sodium atoms, causing them to emit light in the yellow spectrum.
Sodium vapor lamps have a long lifespan, producing high levels of light for up to 24,000 hours. They also have a high energy efficiency, making them a cost-effective lighting option. Additionally, their yellow light is effective for reducing light pollution.
One disadvantage of sodium vapor lamps is their limited color spectrum, as they only produce light in the yellow spectrum. This can make it difficult to accurately perceive colors in the surrounding area. They also have a warm-up time of several minutes before reaching full brightness.
Sodium vapor lamps are often used in scientific research for their ability to produce a specific wavelength of yellow light. This makes them useful for studying the effects of light on plant growth and photosynthesis. They are also used in spectroscopy to analyze the composition of substances based on the light they emit when exposed to a sodium vapor lamp.
