Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
If you replace mercury light with sodium vapour lamp in spectrometer experiment what colors do you observe in the spectrum?
Green, Yellow and Orange.
Why you use mercury lamp instead of ordinary light or sodium lamp in constant deviation?
we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
What do you get when you mix sodium chloride with Mercury?
Mercury will not react with sodium chloride
What is the definition of sodium amalgam?
Amalgam is the word for a mercury alloy. so sodium amalgam is a mixture of sodium and mercury.
In pure yellow light provided by a Low pressure sodium lamp why do some colors remain and others turn different shades of Yellow?
The difference in energy states for the electrons is different in sodium and neon, so they produce different wavelengths (the emission spectrum of each element is different) or colors.
What dominant color appears for sodium street lamp?
The sodium yellow D lines at wavelengths of 588.9950 and 589.5924 nanometers.
What are line spectra and why do they exist?
A spectrum that contains only certain colors, or wavelengths, is called a line spectrum. For every element, the emitted light contains only certain wavelentghs, giving each element a unique line spectrum. They exist for atomic fingerprinting, which is useful in identifying elements. They are also used in sodium-vapor lmaps, which are widely used for street lighting. They are also used in "neon" lights.
What light sources emits only a continuous spectrum a. hydrogen gas b. mercury lamp c. sodium lamp d. incandescent lamp e. laser?
d. incandescent lamp
What is the balanced formula for mercury nitrate and sodium chloride?
Mercury Nitrate: Hg(NO3)2 Sodium Chloride: NaCl
What is Mercury's atmosphere mad of?
Mercury's atmosphere is mainly made out of sodium.
