IGCSE Physics: Refraction Calcualtions and Snell's Law

A revision video looking at the basics of refraction and how to use n = sin i / sin r.

Thank you so much!

[@ollielatter6845]

Very useful. Thanks

thank you so much , great video (:

What are you doing in life now😂

[@halal__boi8250]

very useful. thnx
byt i have 1 question?
in mark scheme its shown that to find sinr we multiply sini with refractive index
is it correct?

[@philsaunders8581]

Sin i = n x sin r
Sin r = sin i / n

WHO KNEW, that you were soo help full?

tysm!!

[@biologyftw9399]

in 8:06 isnt diamond's ref index supposed to be 2.42 ??

[@SaraMohamed-fp3kl]

yes, idk why he used 2.4 only
the answer would be 55.86 if rounded to 2 d.p or just 56 to 2 significant figures when using 2.42 as the refractive index

[@elyas1969]

i dint understand the sin

[@sheca8699]

Am I the only who got 55.2?
