Hi, how do you complete Fig. 1 to show how the ray continues after point Q? Could I have an explanation on how to get it too? Thank you!

I assume that the angle of incidence is indeed 50.
This exceeds the critical angle of 42, so the light Ray will undergo internal reflection, that is, you will draw a light Ray which reflects at the horizontal surface with an angle of reflection of 50. This light Ray exits the curved surface unrefracted at all.
