Why does the light passing through a prism get bent in the same direction twice?
($\phi_2 < \theta_2$)
For a beam of light, dispersion will cause different wavelengths of light to bend in different angles, but they will all bend in the same sense.
Hope this helps.

Dispersion of $E$ and $p$
No, $∆E^2$ is not $2\Delta E$: $$E^2 = p^2c^2 + (mc^2)^2$$
$$\delta(E^2) = \delta(p^2c^2) + \delta [(mc^2)^2]$$
$$ 2E.\delta(E) = c^2(2p.\delta(p)) + 0$$
$$\delta(E) = \frac{pc^2}{E} \delta(p)$$
