Understanding Frequency in Open and Closed Organ Pipes

AI Thread Summary
The discussion clarifies the frequency representation for open and closed organ pipes. It confirms that the drawings of sound frequencies for both types of pipes are correct. For the open pipe, both odd and even harmonics are present, while the closed pipe only supports odd harmonics. This distinction is crucial for understanding the acoustic behavior of each pipe type. The explanation helps resolve confusion regarding the frequency characteristics of open and closed organ pipes.

I have to draw frequency on an open and closed pipe. The top horizontal row is open organ pipe and the second horizontal row is a closed pipe. I have draw the frequency of sound on these but the open entrance of the sound is what is confusing me. Are these correct?

Yup, they are drawn correctly. Note that for the open pipe, the even harmonics also work, it's just for the closed pipe that you only have to consider the odd ones only.
 

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 .
