After the plancks constant question I messed up and the last question I was just writing anything to fill the lines cause I didn't have time. Unit 1 was definitely better for me. I really hope the grade boundaries are low.
I wrote electromagnetic waves have the same speed so when frequency increase the wavelength decrease and when wavelength increase frequency decrease to equate the speed. and so there will be atomic spectra line showing each wave and its wave length and frequency

Hey there, last question was quite easy..you were supposed to say that the atoms of the element ( I think it was sodium ) get excited and move to higher energy levels, later, when they do return, they emit photons- only certain energy levels are possible... energy of the photon must equal the difference in the energy levels and as a result, there are only limited no. of energy differences corresponding to the set frequency and wavelength
