AI Thread Summary
In coherent population trapping (CPT) experiments, key factors influencing the CPT signal amplitude include the temperature of the rubidium vapor cell, the pressure of the buffer gas, and the incidence intensity of the laser. To increase the amplitude of the CPT signal, adjustments to these parameters may be necessary, particularly focusing on optimizing the laser intensity. Understanding the relationship between laser intensity and CPT signal amplitude is crucial for enhancing signal strength. Experimentation and fine-tuning of these variables can lead to improved CPT outcomes. Further insights or detailed guidance on this relationship are sought for better experimental results.

In the experiment of CPT( coherent population trapping),we always consider some questions,such as :the temperatue of rubidium vapor cell, the pressure of the buffer gas ,and incidence intensity of laser. if we just want to increase the amplitude of the CPT signal ,what should we do. And I hope to learn the mode about the relation between the incidence intensity of laser and the CPT signal amplitude.

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
