How to get beat frequency from graph

AI Thread Summary
To determine the beat frequency from the beat envelope of two intersecting waves, the formula fb = f1 - f2 is used, where fb is the beat frequency and f1 and f2 are the frequencies of the individual waves. The discussion suggests that obtaining the frequency of the actual wave may not be the correct approach. A link to HyperPhysics is provided for further explanation on the concept of beats in sound waves. Additional information regarding the specific waves involved may be necessary for a complete analysis. Understanding the relationship between the frequencies of the waves is crucial for calculating the beat frequency accurately.

how do you get the beat frequency from the beat envelope of two intersecting waves as in the attachment

Homework Equations



fb=f1-f2

The Attempt at a Solution


i thought maybe to get the frequency of the actual wave but don't think that's right

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}...
