AI Thread Summary
The discussion revolves around calculating frequency in wave motion using the equation V = fλ. The user is trying to determine frequency (F) given a period (T) of 4.5 x 10^-4 seconds and a wavelength (λ) of 2.0 x 10^5 cm. The calculation shows that frequency is found to be 22 Hz, derived from F = 1/T. Subsequently, the wave speed (v) is calculated as 4,400,000 m/s using the values for frequency and wavelength. Clarification is requested on the full problem statement for better understanding.

Homework Statement


just wondering how we got T when the equation is V=fλ i assume that this is one oscillation.

T=4.5x10-4
F=?
λ= 2.0x10⁵cm

Homework Equations


V=fλ
F=1/T

The Attempt at a Solution



F=1/4.5x10-4
F=22 hz

v= fλ
v= (22) (2.0x10⁵)

v=4400000 m/s

Please post the full problem statement. I don't understand what you are asking.
 
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}...
