Homework Help: Optics: light refraction in prisms

  1. Aug 8, 2014 #1
    Could you please check the following problem?
    The book made an approximation. I didn't in my method. But the difference seems considerable. Did I make a mistake?

    Your analysis looks good. I think maybe the textbook was assuming a different relative orientation between the prism and the wall. See attached figure. But the problem statement is not clear on this point.

    EDIT: I get it now.
    But, would using that approximation be fine for my picture?
