Describe how the laser transitions are arisen.
The given energy level diagram could describe how the laser transitions arise.
Collisions in between the He atoms and Ne atoms because of excitations. The 2s states (as E3 and E5) of He are meta stable, therefore collisions of He atoms into this high state cause excitations into the Ne atoms. At last, the stimulated emission takes place in between E5 and E2leading to the emission of wavelength as:
ΔE = 20.66 - 18.70 = 1.96eV
that is Λ = hc/ΔE
= (6.63 × 10-34 × 3.0 × 108)/(1.6 × 10-19 v 1.96)
= 632.8nm

the magnetic field at a dictance of 2cm from the axis of a straight conductor carrying current is 12mT.Find the currentin the conductor?
Internal Resistance of Circuit: As mentioned earlier in the section on batteries, every source of electricity, such as a cell or generator has resistance to current flow called
ohmmeters: The use of ohmmeters is somewhat more involved. Most importantly when measuring resistance the circuit power must be switched off, power is derived from within the i
