AI Thread Summary
Materials that reflect sound waves vary in effectiveness due to their density and surface texture, with denser materials typically reflecting more sound. Different mediums exhibit varying critical angles due to their refractive indices, which depend on the material's properties. When sound waves refract or diffract, their wavelengths change, affecting how they propagate through different environments. Climate factors, such as temperature and humidity, can influence how sound waves interact with obstacles, altering diffraction patterns. Understanding these principles is crucial for grasping how sound waves behave in various conditions.

Homework Statement



Reflection can you list some materials that reflect more than others and for what specific reason does one material reflect more than the other

Refraction why do different mediums have different critical angles

After the sound refracts OR diffracts, how does it effect the wavelength

How does diffraction actually work, like.. does the climate effect the way waves go through obstacles and diffract, if so how?

Does wave length effect how the wave is diffracted if so, does that have any relation to long wave lengths refusing to reflect so they refract, curve into the hollow space which diffracts?(If this is all wrong can someone please tell me how waves actually diffract and why)

Homework Equations


wave velocity = frequency * wave length

The Attempt at a Solution



Read the textbook, what more can i do... please help

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...
