Hi Miss Martins . Thank you for this Longitudinal Wave Test and Exam Questions. I now get the Longitudinal waves topic and it's calculations . If possible may you please provide more Longitudinal waves exam questions and they should be a bit tricky and please guide us through the video😊
Mam , with regards to question 7.3 would i be penalized if i were to first add 1,5s+0,1s =1,6(then divide by 2=0,8),and multiply 0,8 with 340 to get 272 m(using the formula d=s×t)
technically, it should be b because frequency is the number of waves per second and b has more waves that pass in the same amount of time. (let's assume... 5 seconds) if you have two waves, waves c and d and in these waves, c has 6 waves in 5 seconds while d has 4.5 waves in 5 seconds, c would have more frequency than d because more waves per second and therefore, since i stated that pitch and frequency are directly proportional, that would mean that it would also have a higher pitch than d.. hopefully that makes sense. i'm kak at explaining 😅
@@zxmbi3_za689 nevermind! i had some time to think it over and your teacher is confusing loudness with frequency. loudness is directly proportional to pitch but it is inversely proportional to frequency 🙃
Thanks for explaining it better.
Glad it was helpful!💕

Thank you so much ma'am :)

The memo separates the calculations but if you show all your steps you should get awarded all the marks xx❤️
@@missmartinsmathsscience ok Thank you mam♥️🙏
Hi mam my teacher Had taught me that wave A has a higher pitch according to her because a higher amplitude makes a higher frequency. Is she wrong mam?

Good day ma, plz may i ask where did you get that paper?
