Answer 1

It will be destructive interference so it will be a weak reflection.

As one of the wave will go a phase change of pi radians or 180°.Light waves change phase by 180° when they reflect from the surface of a medium with higher refractive index than that of the medium in which they are travelling. ... The phase changes that take place upon reflection play an important part in thin film interference.

So ray reflected from glass 2 have refractive index of 1.4 which is greater than 1.33 so it will have phase change of pi and rays from glass one will does not go a phase change of pi

So when two waves differ by phase of 180° interferes then there is destructive interference
