how did you get 48.8 for critical angle because I typed in 1/1.33 in my calculator and got something else

[@btecappliedsciencehelp]

SHIFT Sin (1/1.33) =48.8

Hello. I can not find chemistry unit 5. Do you have it sir ?

[@btecappliedsciencehelp]

do a search for Bryson Chemistry on UA-cam
he is a colleague of mine

[@ammorning.5984]

@@btecappliedsciencehelp Okey thank you

[@ChloeFletcher-t7p]

why is it sin minus 1

[@btecappliedsciencehelp]

maths lesson if sin(45)=0.707 then sin^-1 (0.707) = 45 its the inverse function
