WASSCE 2022 PHYSICS PRACTICAL ALTERNATIVE B QUESTION 2 ( REFRACTION OF LIGHT )

This video explains an experiment to determine the refractive index of a rectangular glass prism. Please record all values under each column to equal number of decimal places in the table of values.

[@ekanefestus4868]

Great. The slowest learner will get it straight here sir. God bless you sir

[@RossyBeauty-yh4ys]

Amazing 😍😍 since my physics teacher taught me I don't know it...Thank God I find your program on KZbin so interesting.keep the good work Sir 💯😍🙏

[@HaajaraAbdallah]

Thanks sir, this was better than the way I was taught in class 🙏👏

[@daniellapackard9560]

You are good at what you do, much appreciated from this Side

[@brokenexe6652]

Thank you very much sir, you explained this to the very best!

[@hallehayes567]

I love the practical now I'm able to construct rectangular prism

[@collinsnyignandam8463]

Thank you very much Sir you explained it to me ❤❤❤❤much appreciated for the good work done

[@marybrenya2145]

Excellent

[@monalisajacinta9207]

Please how do i confirm the size of my rectangular glass prism

[@sike6285]

Life is tough

[@OpokuaCalo]

I ❤ it

[@IsraelOluomachi]

God bless you sir for the well detailed explanation, what I could not get from class I have gotten it here.

[@gladysokonkwo3824]

Unizik?😅😅

[@MadubuezeFrazzyd]

😂 see them

[@dcutestluv9023]

Thank you this really helped

[@judithmurendi1970]

Thanks sir you know seeing the pins from the prism was the problem which you solve thanks ❤

[@emmanuelfajuke7168]

This is awesome! Kudos to you!!!

[@NadiMonica]

Sir I'm a bit confused at how you got the slope To determine line AB and BC Did you just draw any line or you measured it before drawing it?

[@alphabetatutorials8274]

Draw any lines but Make them as big as possible and you are good to go

[@Nasirissebugwawo]

What a great lesson is this!

[@LadyprophetMercy]

Should you always change it standard form when it is in decimals to plot?

[@Jennifer-pi4xe]

Sir please looking through the prism for p3 and p4 is my problem sir

[@MayowaOluwatoyin]

All you have to do is look through the block and use a searching pin to find where the pin appears to be on the same line a s the image of the two initial pins

[@MayowaOluwatoyin]

I don't know if this was helpful... I'm just trying to help

[@luulsheikh3801]

Am a kenyan student and i can say perfectly understood ❤🎉

[@PaulPeter-vx1zo]

You are correct

[@onyinyechirachel4492]

What if the L^-2 values are not in descending or ascending order does that means is wrong

[@GraceKoomson-kx7xb]

Hi

[@upendomrosso6959]

Good work sir🎉

[@iqratulux8560]

Am in Kenya doing exams after 30mins and I appreciate this❤

[@OnyeaghalaIsaacChibugo]

Please sir, how did you get sin I, because mine is giving me different values

[@Dolphmaster]

Excellent 👌

[@KamwesigyeDerrick-kg3no]

Thanks, is their any way of obtain other angle without drawing them in paper sheets like 45,55,65

[@alphabetatutorials8274]

Yes

[@eseotite7838]

How can we draw the table with tangent values instead

[@hmm...5180]

Bless🙏 Really helped, thanks!

[@SulemanaAbida]

Good job sir

[@xxxcdddcc8176]

🤝💪

[@SunnyOkegbo]

❤ it

[@userjoachimharrison30]

Nice one

[@adefisoyeolorirejoshua5723]

I have a question o

[@tumz2412]

Good job sir 👏👏. Thanks for this so easy to understand, but I think there's a mistake T x 10^-2 I think it is T x 10^²

[@alphabetatutorials8274]

"Thank you for your comment, but it is not a mistake. You can verify this by multiplying each value in the plotted values by 10 to the power of negative 2 and comparing it with the corresponding value in the tabulated results."

[@ZaibAli-z1j]

What is K?

[@IgwechinweMaureen]

Nice sir

[@MansahAdorkor]

thanks sir

[@movietoon1]

Must i do the diagram for all the angles and submite them

[@alphabetatutorials8274]

Yes

[@alphabetatutorials8274]

Yes

[@JonesFavour]

How do I get the weight of the block?

[@alphabetatutorials8274]

You can use electronic balance

[@Ifekaks08]

How many hours is this pratical

[@alphabetatutorials8274]

The physics practical lasts for 2 hours and 45 minutes. There are three questions, and candidates must answer two of them.

[@Ifekaks08]

@@alphabetatutorials8274 oh okay sir

[@U-installet]

im surprised tha is 25 degrees to the normal, it should be far away from the normal, thats like 70 deg to the normal

[@U-installet]

But i love the exaplanations so much. thank you

[@MansahAdorkor]

great 6:31 6:33 6:34
