what is the difference between sodium vapour lamp and mercury vapour lamp?

Answer: The light in Sodium Vapour lamp is from an atomic emission process whereas in Mercury Vapour Lamp it is, finally, from fluorescence emission. The mechanism of light emission in a sodium vapour lamp is simple and straight-forward.

Compact fluorescent bulbs are made of glass tubes filled with gas and a small amount of mercury. CFLs produce light when the mercury molecules are excited by electricity running between two electrodes in the base of the bulb.

Unlike incandescent lamps, xenon lamps do not suddenly burn out. It's more of a gradual process and involves a considerable loss of light.

There is no difference between the two types of bulbs other than the interior surface of the globe. ... Clear light bulbs give off light that is brighter and suitable for everyday applications, such as kitchens and bathrooms.

Himalayan salt lamps supposedly produce negatively charged ions while water molecules from the air attract to -- and then evaporate from -- the warmth of its surface. Those who believe in the health benefits of these lamps give negative ions much of the credit.

In a nutshell, there isn't quite a difference, but a misunderstanding of the terms. Black light is nothing but UVA light, while UV light is basically composed out of UVA, UVB and UVC. So in other words, black light is UV light(450-100nm), covering the 400-320nm spectrum.

According to the Swiss Federal Office of Public Health (FOPH), undamaged energy-saving lamps do not present any danger, as far as is currently known, but mercury vapor emitted by broken lamps are a danger to health if larger quantities of vaporized mercury are leaked, such as if several linear-form mercury lamps, each ...

The tube of a neon light can spell out a word, for example. These tubes emit light in different colors. A fluorescent light, on the other hand, is most often a long, straight tube that produces white light. ... Neon emits red light when energized in this way.

A real Himalayan salt lamp has an orange or warm pink hue, which is its normal colour. But, the colours can vary even in authentic lamps. ... A salt lamp with a white crystal should be more expensive than a pink Himalayan salt lamp of similar size. If it's the same, or cheaper, it's likely a fake.

Florescent UVB Bulbs provide little heat. Situating one near an incandescent basking bulb will ensure that your pet receives UVB exposure each time it seeks warmth. Halogen and Mercury Vapor Bulbs generally emit higher levels of UVB than florescent bulbs, and broadcast it over greater distances.

A vapour is a substance which has experienced a phase change. A gas is a substance which has not, and will not experience a phase change. Vapour is a solid or a liquid at room temperature, that its natural state of matter is either a solid or a liquid.

There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). These lamps are mostly used for street lighting as well as industrial uses. The lamp works by creating an electric arc through vaporized sodium metal. Other materials and gases are used to help start the lamp or control its color.

Many street lights are yellow because they are Sodium-vapor lamp s. They are extremely efficient, certainly compared to old incandescent-bulb technology, so they are cheaper to run. ... Street lights can be orangish yellow because they contain sodium vapor, with that being the color of a bright spectral light of sodium.

There are two main types of barometers: mercury and aneroid. In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. To increase their accuracy, mercury barometers are often corrected for ambient temperature and the local value of gravity.

VS. Bronzing lamps (bronzing bulbs) will create a darker tan and last longer but the tan is achieved at a slower pace than with regular tanning lamps (tanning bulbs). ... Bronzing lamps are less likely to burn the skin than regular tanning lamps because the rays penetrate deeper into the skin.

As mentioned above, high pressure sodium lights contain a lot of red light, a small amount of blue light and very little UV light. For that reason, they are safer for your eyes than most other types of grow lights. That said, HPS bulbs are very powerful and can cause damage merely through their intensity.

An aneroid barometer measures air pressure without using liquid. A mercury barometer measures air pressure using liquid mercury.
