When an atom jumps from one energy level to a higher one, it is said that it is in an excited state.
You are watching: The specific pattern of colors emitted by excited atoms is called a
As the normal behavior is to be at a ground energy level (unexcited state), the atom tries to return to this state as soon as possible.
When doing this, it emits a photon of a distinct wavelength, which depends on the transition type.
As there are only some allowed transitions possible, the possible wavelengths are a discrete set too.
So, when projected on a photosensitive screen, the different colors form a set of discrete lines, so this specific pattern of colors is called a line spectrum.

Euler’s buckling formula can be expressed as Pcr = π2EI(KL)2 where Pcr is the critical buckling load, E is the column’s Young’s
Eddi Din <679>
Both end hinge-Pcr= 0.98 MN
Both end fix-Pcr=3.9 MN
E= 200 GPa
b=7 cm =70 mm
The critical load given as
For square section
Lets take column is hinge at the both ends :
Now by putting all the values
Pcr= 0.98 MN
Therefore critical load = 0.98 MN
When both end fixed :
L" = 0.5 L
Therefore critical load = 3.9 MN

The security regression testing is used to prevent the re-occurring process. The regression testing is the type of the testing that intends to affirm that a program or code or application changes has not influenced existing highlights and it keeps up the agenda.
The agenda ought to be similarly identified with necessity that was concluded. By checking this both then relapse testing occurs and this won"t reoccurred from next time.
The regression testing improvements groups must ensure that changes, updates and new discharges don"t presents imperfections and vulnerabilities that could be misused by the people.
