IS IT 2.8

I'm really struggling with this and would just like to know if the answer is 29 I've got a bunch of messy working out please

Is the answer 28cm

OMG is the answer 28cm

You told me those were the rules for no phase change. This is really stressing me out now and I'd like some more guidance please I've got 4 different answers 😭

There is three unknowns. both n values and lambda

I'm still confused on how to get from the path difference to the wavelength. This was never taught to me and I need to solve this problem Thanks for your help so far

Does Maxima mean the highest positive amplitude and minimal mean the lowest possible negative amplitude? Or is mimina 0 amplitude (in which case a lowest possible negative ampltude would be a Maxima too?)

Someone on stack exchange told me the answer is 29 which doesn't help my confusion

I genuinely don't know what to do with the path difference because it's not of the form n lambda and this has confused me so much. Could I just get someone to give me a worked solution please

I got 29cm as my answer can someone check please.

By minima, we mean a point of 0 displacement, or a point of "maximum" negative displacement? I think this is the root of my confusion.

If we use the idea that the difference in distance between a maximum and minimum is ##\frac{\lambda}{4}##, then we have ##2\sqrt{0.5^2 + (0.119)^2} - 2\sqrt{0.5^2+0.084^2}## ##= \frac{\lambda}{4}## which solving gives ##\lambda = 0.056m##. If we work out the difference in distance between two...

I have found the path difference for the first max but how do I know if this is lambda or not? I am unsure because when I divide the path difference of the minima by this path difference (which should be the wavelength as the first one is 1 lambda), I expect to get a number in the form n + 1/2...
