Answer:there won't be enough atoms that are excited around to undergo stimulated emmision
Explanation:
Stimulated Emission is the process used in laser operations to produce photons.
In stimulated emission a passer-by photon stimulates the atom to emit a photon, identical to the passer-by photon, immediately. The con to this is that the same passer-by photon could instead get absorbed by a de-excited atom. Therefore, aside of atom excitation we need to use witty ways to insure that there are more excited atoms that could use the passer-by photon for stimulated emission than there are de-excited atoms.
Photons produced by this stimulation have the same wavelength which enables efficiency as all photons are emitted into the same node.
Answer:
<h2>
<em>220.698Hz</em></h2>
Explanation:
The fundamental frequency f₀ is expressed as f₀ =V/2L where;
V is the speed of the string = 
m is the mass of the string
L is the length of the string
T is the tension in the string
f₀ = 
Given datas
m = 5.69g = 0.00569 kg
T = 440N
L = 0.630 m
Required
Fundamental frequency of the steel piano wire f₀
<em>Hence the frequency of the fundamental mode of vibration of the steel piano wire stretched to a tension of 440N is 220.698Hz</em>
