SHM and why does the frequency not decrease?

AI Thread Summary
The discussion centers on the confusion regarding the frequency of a damped harmonic oscillator, specifically why it remains constant despite energy loss and decreasing amplitude. Participants clarify that for a harmonic oscillator, frequency is independent of amplitude, meaning it does not decrease even as energy is lost to damping. The decrease in positive peaks is attributed to damping effects, although the exact reason for this selective decrease is not fully explained. The conversation highlights the need for further understanding of the equations governing these phenomena. Overall, the key takeaway is that frequency remains constant in a damped harmonic oscillator, despite the reduction in amplitude.

Hello, I don't get it why does the frequency not decrease? As this i assume is damping and frequency must change.
And why do only positive peaks decrease?2 Not sure about equations needed.

3.I thought that as it is damped, Energy is lost as heat. Thus speed decreases, therefore, it takes a longer time to complete an oscillation.Thus, frequency decreases, however, the mark scheme says that it is constant
The part about decreasing peaks is due to damping(I assume) but I do not have a clue why only positive peaks decrease.

Please help, I am very confused. Thanks

Why would the frequency decrease? For a harmonic oscillator frequency is independent of amplitude.

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 '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 .
