Relativity, Resnick

Here, for calculating t

_{2}, w.r.t. ether frame, light is moving along the triangular path as shown in Fig. 1.7 with speed c.

w.r.t. interferometer frame, light is moving along the straight path with speed c##\hat y## - v ##\hat x## while going up and with speed -c##\hat y## - v ##\hat x## while going down.

So, t

_{2}= ##( {2 l_2})/ {\sqrt (c^2 +v^2)}##

What is wrong here?

In page no.21, it's written If M

_{1}and M

_{2}are nearly(but not quite) at right angles.

Why can't we take "quite right angles"?
