1. ### Nodal lines and single slit experiment

Thanks for your help! I had mixed up nodal and antinodal lines originally.
2. ### Nodal lines and single slit experiment

So that would suggest that I'm right? 2nd nodal line = 2lambda
3. ### Nodal lines and single slit experiment

Oh okay. The formula is PD = (n)λ but the thing is they have to be out of phase(nodal line) for the minimum to appear. So minima appear where there are nodal lines present. Thus of which leads to being 1λ, 2λ, etc out of phase
4. ### Nodal lines and single slit experiment

I actually have an attachment if you can see it(I'd imagine it'd be a bit hard... but the diagram isn't really too useful) Okay so I have had the wrong idea then. Would it be 1λ/2 and 2λ then?
5. ### Nodal lines and single slit experiment

Homework Statement The diagram above shows a single slit with lines marking the direction to a point P in the diffraction pattern. Two wavelets at x and y pass through the edges of the slit as shown. The possible value for path difference, py-px, that places P at the second nodal line next to...
6. ### Wave interference?

I believe that any multiple of .5 will create a deconstructive interference?(.5, 1.5, 2.5). Okay! I think I got it now. THank you so much for your help!
7. ### Wave interference?

1/2 of a wavelength ? So they can be out of phase. I ended up getting 583.33 Hz as a potential frequency? I used the speed of sound in the room and divided it by .6 as that is the wavelength
8. ### Wave interference?

Okay; Just to ask. Since i know it is .3m apart, can i use submultiples of this to formulate information for the wavelength? E.g, .1 m -> frequency = 350/.1 ->3500 Hz
9. ### Wave interference?

hi; i just wanted to thank you for the help you have given me. That video was helpful. But I am stuck here, as i know the extra distance is .3m, and i know that they are out of phase and because of this the quiet spot is created. What i don't know is the wavelength nor the frequency. I...
10. ### Wave interference?

I'll be honest this course is osmething I haven't touched for a while as I've been busy with my actual school. I'm rusty on this subject. Pardon my ignorance where necessary, but I believe a quiet spot indicated that the area had a destructive interference? Do you know of any reliable youtube...
11. ### Wave interference?

Homework Statement A student enters Best Buy prepared to buy a pair of speakers. Before he does so, he conducts an experiment with them. He places the speakers 4.0 m apart and connects a signal generator to both speakers that produces a single and consistent tone. (constant wavelength and...
12. ### The Wave Nature of Light

PD = (n-1/2) λ ... PD = 0.3
13. ### The Wave Nature of Light

Hi I am having a rough time with this questoin . Homework Statement Question: A student enters Best Buy prepared to buy a pair of speakers. Before he does so, he conducts an experiment with them. He places the speakers 4.0 m apart and connects a signal generator to both speakers that produces...
14. ### Forces of pulleys

But I'm on the right path here?
15. ### Forces of pulleys
