    Where is 180 deg coming from? What is the angle of refraction from liquid to air? What is the corresponding angle in the liquid?

    Look at theta2, by which I presume you mean the angle of refraction into air. Does it look like 180 deg?

    Yes, "theda2" would be 90 deg.

    You're almost there. Check your thedas, which one goes where.

    (Here again, sin theda1 > 1.)

    Dear physicsbhelp,

    The way you are deleting your own posts I find hilarious, though I don't know why you are doing it. I must share this with others. Hope you don't mind.

    Stop playing these games (deleting your posts after getting help) or you will soon find yourself unable to get any help. :grumpy:
