Photoelectric Material: Frequency, Amplified Cosmic Radiation

AI Thread Summary
The photoelectric effect primarily occurs in metals when exposed to UV light, as lower frequencies like visible or infrared do not provide sufficient energy to eject electrons. Amplifying cosmic radiation is deemed unnecessary since UV radiation from space is largely absorbed by the Earth's atmosphere. The term "photoelectric light" needs clarification, as the discussion seems to focus on "photoelectric material." Cuprous oxide and other non-metal substances can also exhibit the photoelectric effect, indicating that it is not limited to metals alone. Understanding the range of materials and their responses to different frequencies is crucial in this field.

What frequencies of light does photoelectric light react best to? Does it matter? How would it react to an amplified form of cosmic radiation?

Photoelectric light?

The photoelectric effect (when electrons are ejected from a material) usually happens with metals using UV light. Lower (visible or IR) frequencies don't have enough energy to do this. I don't see why one would bother amplifying cosmic radiation. The UV from space is heavily absorbed by the atmosphere.

Imparcticle,
Please define "photoelectric light." ("photoelectric material", as the thread title suggests, perhaps?)

Gonzolo,
I believe you mean "... lower frequencies don't have enough energy ..."?

Oh my god yes! <self-slap in the face> Edited.
 
so I'm very interested in this subject and have never been on a forum, please bear with me.
doesn't cuprous oxide produce a photoelectric effect? i was wondering what else created this effect as well... by definition a photoelectric effect doesn't only exist within metals, but also certain gasses and liquids as well... again please feel free to correct me if I'm wrong.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
