AI Thread Summary
In the equation Intensity = P/Area, P represents Power. The discussion also touches on Max Planck's contribution to quantum mechanics, highlighting that he proposed energy is quantized. The equation E = nhf illustrates this concept, where E is energy, n is a quantum number, h is Planck's constant, and f is frequency. Participants express gratitude for clarifying the meaning of P and its relevance to the topic. Understanding these concepts is essential for grasping the principles of thermal radiation and quantum theory.

Hello!

I just started learning about Stefan-Boltzmann's law and I'm stuck on the word for P in Intensity = P/Area.

Also, does anyone have a quick and easy explanation for how Max Planck started quantum mechanics by saying energy is quantized and how the equation E = nhf says so?

How about Power!

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}...
