Waves Sound and Light Grade 10 Physics Exam Questions

[@L.R_EDITZ]

Mam, u don't know how much you helped me in Physics. I am so grateful to you. You have always assisted us wherever you could. May Gods richest blessings fall upon you❤❤❤.

[@missmartinsmathsscience]

Thank you lovely! I am so happy to know that I have helped you! Let me know what else you'd like to see 🤩

[@ThaboNtsiamo]

Electrostatic plz mam🙏

[@SirKayseven]

Even if i don't understand my teacher but this videos are helpful thank you

[@Sakura-nl6yq]

Writing tomorrow, perfect timing 🙂

[@missmartinsmathsscience]

Good luck! You can do it!

[@kiarasubramanian]

Thank you mam!! This video definitely helped to clear up some uncertainties I had before my exam tomorrow!

[@missmartinsmathsscience]

Glad it helped! :) Good luck!

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?

[@missmartinsmathsscience]

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

[@L.R_EDITZ]

@@missmartinsmathsscience thank u mam🤗

[@zeebee69]

You have no idea how you're helping me..Thanks sooo much ! I write in a few hours time and im so ready now !❤

[@missmartinsmathsscience]

I am so happy xxx 😗

[@ThaboNtsiamo]

@@missmartinsmathsscience thanks mam

[@nduman007]

26:18 also Gamma Rays can be used to sterilise medical equipment

[@linakaalipa8793]

All of this was literally my controlled ( exactly the same words ) Thanks ❤

[@ayandamthembu504]

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)😂❤

[@Scornfulvision]

Can you please do electric circuits for me. And thank you for that I now know how certain answers were supposed to be written

[@missmartinsmathsscience]

Hello! I have quite a few videos on electric circuits exam questions ❤

[@reatilelephogole]

You answered my question I was wondering when will you release a video about waves😅

[@missmartinsmathsscience]

Yay! I hope it is helpful 😁

[@reatilelephogole]

@@missmartinsmathsscience Well it did help 100% on physical sciences Paper 1 is still loading 😅😁

[@L.R_EDITZ]

Mam will you be completing Q6 and 7 of this paper in another video. In Section one, MCQ, i didn't understand 1.5 and 1.6 and i saw it in other past papers but i think you forgot to do it🙃

[@missmartinsmathsscience]

Hello! Yes I can! I think it is electricity and electrostatics? I left those out for this video because I wanted to focus on waves but I can do it for you! 🤗

[@selekaneleseyane9]

May I ask Is the KZN exam paper the same as Gauteng's one?

[@missmartinsmathsscience]

No they generally do different exam papers - but the same work is covered 🤗

[@otlil.e]

5.4 the answer is 2,84×10-¹⁹

[@lwazijama1827]

thanks, I thought my calculator was tweeking.

[@missmartinsmathsscience]

Apologies for some reason I wrote it as to the power of negative 10 and not 19!! Thank you for correcting 🥰

[@missmartinsmathsscience]

Sorry, wrote it down wrong! I did get to the power of -19 as well!

[@KamoheloLehola]

Can you make more electromagnetic radiation calculations questions

[@SiphokaziPhelo]

Ma'am can you make revision video for term one🙏

[@missmartinsmathsscience]

Different schools do Different topics in term 1 so it's a bit difficult to do a revision video 😓 what topics did you do?

[@AyabongaDyomfana-vz9nj]

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]

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 ☀️

[@pinkythulisiwebuthelezi6776]

Me watching this a day before exam

[@missmartinsmathsscience]

Good luck 😁✨️

[@siajamnadas]

I’m writing in a few hours lol 😭 thank u miss martins

[@missmartinsmathsscience]

My pleasure I hope it went well😅🥰

[@rothesingo2271]

Mam, please explain how you got 1,75 instead of 0,75 I dont understand

[@missmartinsmathsscience]

1,75 is the number of waves in distance x. I highlight the different waves. I show you exactly where I get the 1 and 3/4 waves from in the video, I label them❤️

[@OliviaQueenNalulyo-rd5gu]

On question 5.4 my calculator gives me the same answer but the exponent is negative 19😢

[@nsovo6770]

bruh same, I thought my calculator was tweaking but she did say she made a mistake on a previous comment I read

[@ThaboNtsiamo]

❤

[@missmartinsmathsscience]

❤️

[@pinkythulisiwebuthelezi6776]

I am speechless

[@missmartinsmathsscience]

Why?😅

[@MduduziMpofu-u2g]

Part 2.pliz😢

[@missmartinsmathsscience]

Check out my waves playlist ❤ I have more videos x

[@LunaJordanSteyn]

Miss 3/4 = 0,75 not 1,75

[@missmartinsmathsscience]

Which timestamp is the question?⭐️

[@missmartinsmathsscience]

I see what you are referring to (at 17:39 ). I am looking for distance x which is 1 and 3/4 of a wave. I do say one a three quarters❤
