AI Thread Summary
To calculate the wavelength of a water wave with a speed of 0.25 m/s and a cork moving up and down 4 times in 8 seconds, the frequency must first be determined. The frequency is calculated as the number of oscillations (4) divided by the total time (8 seconds), resulting in a frequency of 0.5 Hz. Using the formula wavelength = speed/frequency, the wavelength can then be calculated. The confusion arises from distinguishing between frequency and time, as frequency is measured in Hertz (Hz), not seconds. Understanding these concepts is essential for accurately determining the wavelength of the wave.

Homework Statement


There is a water wave having a speed of .25 meter per second that causes a cork to move up and down 4.0 times in 8 seconds
what is the wavelength of the water wave

Homework Equations


v=f times wavelength
T=1/f
x=vt

The Attempt at a Solution


I used the formula wavelength =v/f and I plugged v for 0.25 m/s.
For frequency I plugged 8 seconds but Idk think I did that part right. I'm alittle confused on what 4.0 times in 8 seconds is? Like is it the period?

Do you understand what frequency is? (Hint** time is not frequency. What units does frequency have?)

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 '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...
