Explanation / Answer

Here ,

1)

angle of incidence , i = 30 degree

angle of reflection = angle of incidence

angle of reflection = 30 degree

the angle of reflection at which the beam is reflected is 30 degree

2)

for

angle of incidence i = 0 degree

angle of reflection = angle of incidence

angle of reflection = 0 degree

3)

for the reflection :

the image is laterally inverted.

4)

as water is more optically dense than air

using snell's law

the refracted ray will turn towards the normal
