The diagram is incorrect is it because there should be a weak reflected ray internally before the emergent ray?
nope
hints:
1. what is the critical angle value for the glass block?
2. what is the angle of incidence at side KL?
3. what phenomenon would occur at side KL?

Total internal Reflection
Thanks a lot!!
No wonder they said hence or otherwise draw the arrows representing light rays
The previous question calculating the critical angle
However I need help for the open ended question 4a) please thank you
