Releasing Electrons with a color filter

AI Thread Summary
To release electrons from a cathode using a color filter, understanding the photoelectric effect is essential. The discussion highlights a conflict between wave-particle duality in physics, questioning how light interacts with the photocell. Inserting a color filter reduces the voltage of the light, which impacts electron release from the photocell. The participants are puzzled about the mechanism behind this voltage loss and its relation to the work function of metals. Clarification on how the color filter affects electron release is needed for a complete understanding.

Homework Statement



Simple question we have to answer:

(Physics) How do I release the electrons from the cathode with a color filter? (The so called
Photoelectric effect)

Homework Equations



none

The Attempt at a Solution

[/B]

Here we have a conflict , the so called wave-particle duality, if I recall it correct.

I have no idea what could cause to release the electrons from the photocell. In the experiment the light lost voltage after inserting a color filter, making the electrons release from the photocell. (cathode and anode)

But why exactly, I cannot imagine. Perhaps because the color filter absorbs the electrons? (Makes no sense though.)

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}...

Thread 'Struggle to understand the concept of the 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...
