Relationship between say an opening and the wavelength

AI Thread Summary
The relationship between an opening and wavelength is crucial in understanding wave diffraction. Longer wavelengths result in greater diffraction, which explains why AM radio, with its longer wavelengths, can transmit better around obstacles compared to FM radio. The size of the opening also plays a role, but its impact may not be as significant as the wavelength itself. A smaller opening with a larger wavelength will indeed lead to increased diffraction. Overall, the interplay between wavelength and opening size is essential in wave behavior.

I just have a basic question about waves and diffraction because i am not really clear on that part.

What is the relationship between say an opening and the wavelength. For example i am not sure if there is a smaller opening with a large wavelegnth, will a lot of diffraction occur.

With my limited knowledge I can tell you this much: longer wavelengths cause more diffraction. This is why AM often works better around hills and such than FM--AM has longer wavelength. As for the size of the hole, I don't know for sure but I think that that is not very important--don't trust me for sure though.
 

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...
