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🙏

[@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

[@Sakura-nl6yq]

Writing tomorrow, perfect timing 🙂

[@missmartinsmathsscience]

Good luck! You can do it!

[@MbaliMliqika]

I'm writing tomorrow and I can't understand anything 😢

[@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!

[@SirKayseven]

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

[@linakaalipa8793]

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

[@L.R_EDITZ]

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🤗

[@shaunshaun1409]

you the best

[@nduman007]

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

[@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 😅😁

[@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 ❤

[@DziphathutshedzoMakhokha-t5f]

Im in grade 10 this year, and I think that i found the right person ❤️🙌🏿, whom is gonna assist me with physics

[@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!

[@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 🤗

[@MbaliMliqika]

3.5 how maam please make me understand where does it come from😢

[@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! 🤗

[@siajamnadas]

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

[@missmartinsmathsscience]

My pleasure I hope it went 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?

[@pinkythulisiwebuthelezi6776]

Me watching this a day before exam

[@missmartinsmathsscience]

Good luck 😁✨️

[@WalterMbatha-p4u]

Question 4,4 was tricky 😅

[@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 ☀️

[@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

[@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❤️

[@ThaboNtsiamo]

❤

[@missmartinsmathsscience]

❤️

[@pinkythulisiwebuthelezi6776]

I am speechless

[@missmartinsmathsscience]

Why?😅

[@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❤

[@MduduziMpofu-u2g]

Part 2.pliz😢

[@missmartinsmathsscience]

Check out my waves playlist ❤ I have more videos x
