Could you make your voice louder while explaining, i had to put my headphones volume on FULL just to be able to hear what you were sayin innit? Thanks for having subtitles tho
The inverse sin of 1, ie sin-1 (1) is a very special value for the inverse sine function. Remember that sin-1(x) will give you the angle whose sine is x . Therefore, sin-1 (1) = the angle whose sine is 1.

I honestly believe I have spend over 24 hours watching videos from organic chem tutor starting with pre-cal through cal 2 and both physics 1 and 2
i fell asleep during my zoom class during this explanation in class so this is a life saver like ur the best bro
Same😅
M let
Nobody cares
responding to a 3 year old comment so say no one cares is crazy lol@@epiphanyikuru8089
@@epiphanyikuru8089 this is what someone would say that's related to their life experiences
This dude is fr carrying my pre-med subjects
Here to study for my test on EM spectrum and Optics on Friday for my Physics Class Thank you so much !!
thank you so much, you're a life saver.
This has helped me a lot. Thank you from the bottom of my heart 😭💜
You should be able to teach us this weekend way home through on -line
Tani maka answer kos exam ani part. Thank you!
Great vid I put the stuff on my notecard for exam appreciate the thorough video 😁
Please make a video on thin-film interference
@TheOrganicChemistry Tutor, Thank you for the explanations, they are very straightforward.I would appreciate if the questions are bolder.
Thank you so much for this video❤❤❤ you are really a life saver❤🙏🙏
thank you very much Mr. organic chemistry.
Ur explanation is very much helpful 😁. If possible can u make a video on apparent depth and normal shift
Best explanations ,thank you.
x in the last problem should be 41.73 as 48.27 would be the other angle. 90-47.27 gives us the angle depicted as x.
You r thr best physics techer

You are simply the best 🎉🎉
Thank you very much Sir for this information
Very helpful! Thank You
Just to let you know, it is difficult to discern the dark blue color with the black background.
It's really useful for me .thank u
Amazing video ... thanks yet again!
THANK YOU
Thank you!
it helped me alot

Love from Bangladesh 😊😊
Perfect
Will the angle of refraction from diamond to air be equal to 60° in the air water diamond problem? 10:00
Thanks man
I did understood,but I'm kinda confused with sine -¹(........) Like what's the -¹ for?
The inverse sin of 1, ie sin-1 (1) is a very special value for the inverse sine function. Remember that sin-1(x) will give you the angle whose sine is x . Therefore, sin-1 (1) = the angle whose sine is 1.
What is the value of sin-1
I'll be leaving 50 hearts in the comsec if I pass the exam😅 be back soon hahaha
THANKSSSS ALOTTT REaalllyy helppeed me!!!!!!!!!!1
Your voice was so romantic 😅
Thanks bro, ur the best 😇
very useful
What is the unit of measurement of the answer at 2:19?
n = index of refraction so there is no unit to it
it's just a ratio
@laceyharrison384, reason to this is because the units cancel out, thus becoming no units.
dont you allways have to change the wavelength in meters?
At 14:00 why can you just neglect n2sinθ2 from a physics standpoint?
when i plug in 1Sin(30) into the calculator i get -.98, not .5 like in the problem, why is that??
you have your calculator in radians. it needs to be in degrees for these type of problems :)
how did it become22°?
does anybody know how to type it on calculator how did he find the angle of refraction😭 please i badly need help
in my exams to
❤❤❤❤❤
شنو هذا ياخي ما فهمت شي
miss malak said n is bigger in water so light is faster in water ur wrong smd
THANK YOU SO MUCH
