AI Thread Summary
The cutoff wavelength is the maximum wavelength of light that can still cause the photoelectric effect, meaning it defines the threshold for photon energy to release electrons from a metallic surface. In the context of the assignment, the cutoff wavelength can be calculated using the work function and the stopping potential provided. For light with a wavelength of 500nm and a stopping potential of 0.45 V, the maximum energy of emitted electrons and the work function can be determined to find the cutoff wavelength. Understanding this concept is crucial for solving modern physics problems related to the photoelectric effect. The cutoff wavelength is essential for linking photon energy to electron emission in various applications.

I'm doing my modern physics assignment and the question asks me to calculate a few different thigns - one of them being the cuttoff wavelength. My question is WHAT IS IT? I looked in my textbook and didn't really see anything about it so any help would be appreciated. Thanks :smile:

It can be either one of these 2 things:either connected with the photoelectric effect,or with X bremsstrahlung.
Tell us in what context does it appear...

Yah perhaps I should have posted the question too :wink:

Light of wavelength 500nm is incident on a metallic surface. If the stopping potential for the photoelectric effect is 0.45 V, find a) the maximum energy of the emitted electrons, b) the work function, c) the cutoff wavelength.
 
Okay,then.You should have known this issue from the textbook.It's the maximum wavelength the incident photon may have as to still produce photoelectric effect...

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}...
