Hi sir, I would like to say thank you for all the knowledge that i get from watching all of your videos from form 4 to 5 topic. It has helped me a lot. Im a batch 04 and im gonna sit for spm in 2 more months. Thank you so much once again :)
Thank you for all your help until now, sir. Your videos have really helped me revise for my spm exam. Your video explanations are just as good as your explanations in class. Thank you very much, sir. 😁👍
Hi sir about the smoke detector, so the smoke must be high in frequency is it that the detector is able to detect it?I’m a bit confused there, smoke has frequency?or is it because of the temperature?
Hi. The smoke block the light that brings photon with enough frequencies to produce photocurrent. Once its blocked, no photocurrent produced so circuit breaks.
thankyou sir sangat hensem dan fham
THANK YOU SIRRRR🤧 lame dah tak faham quantum

terima kasih cg
cg nk tnya mmg light tu dtg dari satu arah je ke?ada kemungkinan tak utk light source tu datang dari banyak arah??
Boleh ja dr mana2 pun
thank you sir :D!
tenkiu sir
Sir, frekuensi ambang dan fungsi kerja ni merujuk pd elektron dlm permukaan logam ke?
Betul. Logam hold elektron tak bg keluar. f light kena lebih besar dari f ambang baru jd fotoelectron
Thank you sir :D
n apa kesannya??ke sama je
Mana2 arah pun boleh. Kesan bergantung pada frekeunsi cahaya tu.
Please help me sir I'm form 4 saints student and I cant understand physics
Hi suriabalan. Where are you studying currently?
@@yusfiyusop I'm studying in Sekolah Menengah Sri Acmar in klang
Please sir I really need your help
