Questions about Wave Period and Radio Wave Wavelength

AI Thread Summary
The period of a wave is defined as the time it takes for one complete wavelength to pass a given point, not the number of waves passing through a point. To calculate the wavelength of a radio wave with a velocity of 3x10^8 m/s and a frequency of 10^6 Hz, one can use the formula wavelength = velocity/frequency. This results in a wavelength of 300 meters. Consequently, 100 cows, each measuring 3 meters, would fit within this wavelength. Understanding these concepts is crucial for grasping wave behavior in physics.

Hi all

I was absent from school when these were done, so I missed out on some of the work (which is highly regreted).

I'm just needing to know a few things, hopefully you guys can help me out here.

The period of a wave, that's the amount of times a wave passes through a certain point, right? please correct me

and this question, How many 3m cows would fit into a wavelength of a radio wave of velocity 3x108 and frequency 106Hz.

Thanks alot, I appreciate it.
 
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}...
