Grade 12 Physics | Photoelectric effect| Full lesson

Optical phenomena and material properties

In this lesson you will learn the necessary theory on the Photoelectric effect:

- the duality of light
- the wave nature and the particle nature of light
- what is a photon
- how to calculate the Energy of a photon
- how to calculate the work function of a metal
- what is the threshold frequency
- how does intensity affect the Photo-current

All of this compressed into one lesson.

Finally I also tackle one past-exam question from SC/NSC 2019 Exam

Enjoy!!!

Just Went From Level 1 In Physical Science To Level 3 In First Term And From Level 3 To 5 In Second Term And Aiming For 7 In My Examination

I watched this in 1.5x speed and understood in 30 minutes 😭 you explained in 30 minutes what my teacher couldn’t in 3 hrs.

Law of Mlungisi-States that the more you watch his videos, the more you will pass Maths and Science at lesser work done per unit time

[AkhanyaMatandabuzo]

I have a good likely of finding this channel before my trial exam

[trevorkhetsekile]

Thank you sir. Your videos really help us out here. I got 93% for Physical Science in September and I am aiming to get 100% in my final exam

my guy, you the reason why I get distinctions in physical science#classof2021

All of your videos are different in their own way✔🙂. The is a very painful thing, watching a lesson or a video several times but still don't understand what is happening, I've experienced that and I ended up accepting that physics is not 4me. but now that I am a part of this family I love physics and I know every chapter from the start😊 I understand everything, because of you Sir, you are a blessing from God 😊💗

[oarabilesiyabongamaine]

Every since i have been watching your channel i have improved in my physics,
I went from level 3 to level 6.

[DylanSwarts]

Thanks for your hard work in producing these videos! I'm a 90% Physical Science student and it always helps to have good videos that I can use as refreshers or to build a better understanding on fundamental concepts I may have forgotten over time.

[georgejungle]

Man bless your Soul I have my prelims tomorrow and I just want to say thank you you've saved me and a lot of others heartache. I hope more physics students discover this channel and again thank you.

[BoundBy_Faith]

this section does not require that much work and energy tbh, you are saving us from 100 pages of textbooks just to grasp these basics you covered in less than an hour

[ntsakisoo.m]

I wish I found this channel before my prelims, I’ve watched all of them and I understand my work. 😩🤝

[MafefeAcademyTutors]

Man, you're good with this. I am a civil engineer, but I missed some of the most essential lessons. Thanks for helping us catch up thanks.

[Movies]

Your lessons just made my revisions simple and manageable ❤️👌🏾

[bonniem]

sometimes i get teary eyed mid video because i appreciate you sharing your teaching ability to help those of us that struggle to understand. Thank you so much

[calvinbafshoe]

Interesting chapter I love it. One of the chapters I really need to focus on and do research on when I will be doing my master's degree. I relate to the energy of the photon as the force applied and work function as the static friction of the object. In order for a person to move/accelerate an object, the person must overcome the static friction of the object. And so in this case the energy of the photon which is force applied must be greater than the work function for the electrons to be emitted.

Thanks sir in did your are the best I'm now verifying everything that my teacher has thought me. Last year I have got Level 5 in Physical Science this year I'm going to get Level 7 it is because of your presence in my lessons 🙏🏼📚

[arttaku]

I have been struggled in this lesson for so long, thank you for making this video you really cleared all my confusion. Appreciated it😭❤️

[mlungisijunior]

Good day, Sir....I'd like to start by applauding you for all your phenomenal physical science videos and teaching techniques, they really do come in handy and are much appreciated....But I have a request for you to please dig further on the photoelectric effect and perhaps do a video on the emission and absorption spectrum as I have a problem understanding the concept....Looking forward to your response Sir

[Kumandra_Bullock]

I'm so gonna slay my exams with these...thank you much
