AI Thread Summary
The discussion centers on determining whether the red or violet end of the spectrum is closest to the central maximum in diffraction patterns. It emphasizes the need for understanding diffraction concepts, specifically referencing single slit, double slit, or diffraction grating. Participants suggest reviewing relevant equations and studying the diffraction section of textbooks to grasp the topic. The impact of decreasing the distance (d) on the diffraction pattern is also mentioned, implying a need for further explanation. Overall, a solid understanding of diffraction principles is essential for addressing the questions posed.

Is the red or violet end of the first order nearest the central maximum? Justify your answer. What would you observe if d were decreased. explain.

I have no idea what the central maximum is. what equations do i use? i am so lost. please help me out. thanks.

Crack open the textbook, you have some studying to do in the diffraction section (either "single slit," "double slit," or "diffraction grating").
 

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...
