Water Waves - Universal Wave Equation

AI Thread Summary
The discussion revolves around understanding the universal wave equation in the context of water waves. The user calculates the frequency as 0.75 Hz based on a given number of cycles over time. There is confusion regarding the wavelength (λ), with a mention that 28 meters is not the wavelength but a factor related to it. The definition of wavelength is clarified as the distance between consecutive crests or troughs of the wave. The conversation emphasizes the importance of correctly identifying the wavelength in wave calculations.

Water Waves -- Universal Wave Equation

Homework Statement



Attached.

Homework Equations



v=fλ

The Attempt at a Solution



f= cycles/time
f= 45/60
f= 0.75 Hz

The trouble I am having is wondering if λ is 28 m or do i have to do something else to find λ?

No, the wavelength itself is not 28, but 28 is a factor of wavelength. One wavelength is the distance from crest to crest, or trough to trough, or however you want to see it. It is however long the wave is until it repeats itself.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
