Explanation: Hexa is a prefix means 6. Sulfur Hexafluoride is expressed in SF6
This Question has mistakes.Correct question is
An undamped oscillator has period τo=1.000s
, but I now add a little damping so that its period changes to τ1=1.001s.
What is the damping factor β? By what factor will the amplitude of oscillation decrease after 10 cycles? Which effect of damping would be more noticeable, the change of period or the decrease of the amplitude?
Answer:
β=0.28 /sec
Amplitude=0.0606
Explanation:
![T_{o}=2\pi /w\\T_{1}=2\pi /\sqrt{w^{2} -\beta^{2} }\\ As\\T_{o}=1 \\T_{1}=1.001\\From T_{o}\\w=2\pi \\So\\T_{1}=w/\sqrt{w^{2} -\beta^{2} }\\\beta =0.00447w\\\beta =0.00447(2\pi )\\\beta =0.28sec^{-1}\\ Amplitude=Ae^{-\beta t}\\ after\\ t=10T_{1}\\so\\Ae^{-\beta(10t_{1}) }=e^{-\beta(10t_{1}) }\\=e^{-\(0.28)(10)(1.001) }\\Amplitude=0.0606](https://tex.z-dn.net/?f=T_%7Bo%7D%3D2%5Cpi%20%20%2Fw%5C%5CT_%7B1%7D%3D2%5Cpi%20%2F%5Csqrt%7Bw%5E%7B2%7D%20-%5Cbeta%5E%7B2%7D%20%20%7D%5C%5C%20As%5C%5CT_%7Bo%7D%3D1%20%5C%5CT_%7B1%7D%3D1.001%5C%5CFrom%20%20T_%7Bo%7D%5C%5Cw%3D2%5Cpi%20%5C%5CSo%5C%5CT_%7B1%7D%3Dw%2F%5Csqrt%7Bw%5E%7B2%7D%20-%5Cbeta%5E%7B2%7D%20%20%7D%5C%5C%5Cbeta%20%3D0.00447w%5C%5C%5Cbeta%20%3D0.00447%282%5Cpi%20%29%5C%5C%5Cbeta%20%3D0.28sec%5E%7B-1%7D%5C%5C%20Amplitude%3DAe%5E%7B-%5Cbeta%20t%7D%5C%5C%20after%5C%5C%20t%3D10T_%7B1%7D%5C%5Cso%5C%5CAe%5E%7B-%5Cbeta%2810t_%7B1%7D%29%20%7D%3De%5E%7B-%5Cbeta%2810t_%7B1%7D%29%20%7D%5C%5C%3De%5E%7B-%5C%280.28%29%2810%29%281.001%29%20%7D%5C%5CAmplitude%3D0.0606)
Explanation:
The figure that accompanies the question shows the wavelenghts of the photons emitted according to Balmer series transition , from energy levels (n) 3, 4, 5, and 6 to the energy level (n) 2, in hydrogen atoms.
These are the values shown in the figure
Transition wavelength of the photon emitted
nm
from n = 3 to n = 2 656 <------------- this is the value requested
from n = 4 to n = 2 486
from n = 5 to n= 2 434
from n = 6 to n = 2 410
The wavelength of a photon emitted from the n = 3 shell in hydrogen is the first data of the table, i.e 656 nm.
Using the conversion factor from nm to m that result is:
656 nm * 1 m / (10^9 nm) = 656 * 10 ^ - 9 m.
C. Spectroscope
Spectroscope is the instrument that can break down electromagnetic light into its constituent parts.
It is a device that helps us identify what things are made out of. It takes the light and splits it up into its component colors.
