Please tell about the calculation part after finding r=0.42 , i cant understand how...?
Dear Student,
The question is related to the snell's law i guess. And here we are calculating angle of refraction 'r'.
So, we are getting( referring to image given) ,
sin r = 0.42
so, r = sin-1(0.42)
= 24.83o
= 24o50' approx.
Hence angle of refraction is 24o50' approx.
Regards
