British Physics Olympiad 2019
Can someone help me with 10 a ii? I don't understand why they used 0.22x10^-9 for the value of wavelength instead of the calculated 0.19x10^-9
I linked the pdf below & MS:

I honestly dont know why they use that value - maybe a ms mistake?
In this video they use your value but they get the ms answer (28:16).

When I type it in the calculator it gives a value of 1.05x10^-15 J?
((6.63x10^-34)(3x10^8))/0.19x10^-9
I'm not typing it wrong am I???
nah nah I got that too
I think maybe the ms is wrong or this is not a correct method (for whatever reason was overlooked by the ms and video).
