Two-point source interference pattern

AI Thread Summary
The discussion revolves around calculating the angles of nodal lines in a two-point source interference pattern created by in-phase sources. The sources are spaced 2.0 m apart, operating at a frequency of 1.0 Hz, with a wavelength of 0.60 m. Participants suggest using the formula sin(theta) = (n - 0.5)(λ/d) and substituting various integer values for n. While it may seem tedious, only a limited number of n values will yield relevant results, and using a spreadsheet can streamline the calculations. The focus remains on efficiently determining the angles for the nodal lines in the interference pattern.

Homework Statement



A two-point source interference pattern is generated by sources operating in phase at 1.0 Hz. The sources are 2.0 m apart and the wavelength of the waves is 0.60 m. At what angles, measured from the centre line of the pattern, are the nodal lines produced located?



They want to sub in for various values of n? or am i missing something it seems to simple? i am using sintheta=(n-0.5)(\lambda/d)

Welcome to PF!
Yes, sub in n = 1, 2, 3, ... It looks like an infinite amount of work, but you will find that only a few values of n need be worked out. It is a little repetitive - a spreadsheet formula would be quickest!
 
thanks
 

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 .
