AI Thread Summary
To find the wavelength, frequency, and velocity of a wave given that a series of wave crests pass a point in 0.50 seconds, the correct answers are 3.8 cm for wavelength, 6.0 Hz for frequency, and 23 cm/s for velocity. The question's phrasing implies that the number of wave crests passing in that time frame is essential for calculations. The absence of a diagram or additional measurements complicates the interpretation but does not negate the ability to derive the answers. It is crucial to ensure the question is copied accurately to avoid confusion in solving the problem. Understanding the relationship between these parameters is key to solving wave-related physics questions.

A series of wave crests, all of which will pass a point in 0.50s, find wavelength (cm), frequency, and velocity

The answers are 3.8cm, 6.0 Hz and 23 cm/s...

Can someone explain how to get those answers? I did arrive at an answer, but they weren't right :(.

The statement "A series of wave crests, all of which will pass a point in 0.50s, find wavelength (cm), frequency, and velocity" does not contain enough information to answer the question. Please make sure you copied the question exactly as it was given to you.

That is what the question said... I did omit the diagram, but it's just a simple and plain wave with a line through it, no measurements, no info of any kind.
 

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}...
