for diffraction grating mercury lamp is used not sodium lamp.
Pure mercury is a silvery color, but it can appear to be a different color when it is in compounds or in certain forms. For example, mercury can form colorful compounds such as mercury(II) oxide (red) or mercury(II) chloride (white).
When mercury and iodine crystals are ground together, they react to form a red compound called mercury(II) iodide. This reaction is exothermic, releasing energy in the form of heat. It is important to handle these substances with caution, as mercury and iodine can be toxic.
When ammonia is added to mercury, a white precipitate of an amide complex is formed. This white precipitate is generally insoluble in water and can be further characterized by its crystalline structure. The formation of this complex can be used as a chemical test to detect the presence of mercury ions.
If water had its highest density at 0C instead of 4C, it would mean that ice would sink in liquid water. This would have significant implications for aquatic ecosystems and the Earth's climate, potentially leading to disruptions in ocean currents and marine life.
If you burn glass, it will not melt like other materials such as plastic. Instead, it will turn into a different form of glass known as "glassy carbon." This material can be used for various applications like electrodes and semiconductors.
If the width of the clear space and ruled space in a diffraction grating is made equal, it will result in the zeroth order of diffraction being suppressed. This is because the light will predominantly be diffracted into higher orders due to the equal spacing of the slits, leading to changes in the overall diffraction pattern observed.
Grating spectrum is a spectrum produced as a result of diffraction, as by a grating.Whereas prismatic spectrum is a consequence of dispersion of light by a prism. In grating spectrum you also observe different orders of spectral lines which does not happen in prismatic spectrum. Hope this helps VIBHAV ZUTSHI B.Tech '13 IIT Kharagpur
No, it is a universal phenomenon for all sorts of waves - both transverse and longitudinal.
Mercury Meltdown happened in 2006.
steel will float in mercury
no
When the slit separation increases, the diffraction pattern becomes wider, with narrower central maxima and weaker secondary maxima. Conversely, when the slit separation decreases, the diffraction pattern becomes narrower, with wider central maxima and stronger secondary maxima.
Archer Maclean's Mercury happened in 2005.
Mercury Meltdown Revolution happened in 2007.
level of mercury fall down
They would float on the surface of the Mercury but they wouldn't react with the Mercury.
Mercury causes major neurological problems.
