Mam, at 16:17 you do the method to calculate the wavelength. Is it fine if i use the triangle method for the calculatuions and block out the one im solving for, I find it easier but im not sure if i will be marked right. Like at 16:17, i used the triangle method and i got: Lambda=v/f which gave the same answer. Can i use the triangle method for all the calculations in my paper?

Most definitely! Just remember to always write down the formula as it is shown on the formula sheet first, then you can use the triangle method :D

So Mam with question 1.3 your focus shifts from the theory lowkey to the main components in a wave graph e.g amplitude, Wavelength etc. Because why l say so is l agree loudness is linked with amplitude so as frequency linked with pitch but now pitch isn't on the graph so taking us back to frequency being interlinked with period, then theory comes to play check listing, the higher the amplitude the higher the loudness and we can move on to question itself? (IM WRITING TMR PLAZZZZZZ ANS ASAP)😂❤

Question 3 in 3.4 Ma'am I think you made a mistake the Wavelength is in Millimetres therefore your final answer after you have used V=f.X you must divide it by 100

@missmartinsmathsscience 7 ай бұрын
You're right! Well spotted💓💕 they wanted x in meters which means you must convert that answer to metres to mm! I completely forgot to do that. Everyone makes mistakes and it's such a good reminder to read the question carefully and read it once more after you finish a question so thanks for that ☀️
