Visible spectroscopy is one of the most widely and also most commonly used approaches in chemical analysis. Because that a problem to be energetic in the visible one it have to be colorful: the a substance has actually color, that is due to the fact that it absorbs details frequencies or wavelengths of the visible spectrum and transmits others.

You are watching: Mg emits radiation at 285 nm. could a spectroscope be used to detect this emission?

The visible variety is considered from 380 to 750 nm. The variety of the close to Ultraviolet or Quartz is 190 to 380 nm.

The spectroscope is an instrument that enables us to determine the different regions in ~ the visible spectrum (380 come 750 nm wavelength), in this case the Mg emits radiation in ~ 285 nm so the would fall into the ultraviolet spectrum and would not be clearly shows to the person eye and also therefore could not be detected v a spectroscope.



Answer from: Quest
At preferably height, kinetic energy is converted in potential energy formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j therefore the continuing to be pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m

The pressure increases by 1.0 x 104 n/m^2 because that every meter that depth beneath the surface ar of the ocean. At what depth does the volume that a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge in ~ the ocean"s surface, diminish by 7.5 x 10−10m^3? define the formula past this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. At some point l needs to it is in cubed. Why ns is split by delta v?

Asolid cylinder and a cylindrical shell have actually the very same mass, exact same radius, and turn top top frictionless, horizontal axles. The cylindrical shell has light-weight spokes connecting the covering to the axle. A rope is wrapped roughly each cylinder and also tied to blocks of same masses the are organized the exact same height above the ground. Both blocks are released simultaneously. The ropes execute not slip. Which block access time the ground first? or is the a tie?
