AI Thread Summary
The discussion focuses on the characteristics of lasers that enable various applications, including holography, missile guidance, and medical surgery. Key properties identified include coherence, collimation, and intensity, which are crucial for different uses such as telecommunications and laser cutting. Participants emphasize the importance of conducting personal research to understand these characteristics better. There is a request for clarification and correction of initial answers regarding laser properties. The conversation highlights the need for accurate information and self-research in understanding laser applications.

Have you tried researching on the web yet? What if you searched for something like "lasers for cutting metals".

I tried and saw many books on this topic , but they differ about the characteristics and every book and website say a different characteristic.

That is my trial in order:
1- holography: coherence
2- orienting missiles: collimation
3- star wars: intensity
4- CD and DVD: collimaton
5- medical surgery: intensity
6- telecommunications and fiber optics: coherence and collimation
7- LASER printer: collimation
8- cutting metals: ??

We do not edit wrong answers for you here.

What-all are the properties of lasers that you are using? So far I think I see three: intensity, coherence and collimation. Are there any others? Where did you find those properties?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
