reflection at one plane
scattering nott

Reflection:When the light travels from one medium to another medium it bounces back to the first medium,then it is said to be reflection.
Scattering:The process of splitting of white light into its compounds (VIBGYOR)

this is not right. the definition of scattering given here corresponds to dispersion of light actually.

i think reflection is a surface phenomena bcoz light travels into same medium after reflection but in case of scattering we need a obstacle .it is not necessory that after scattring light will split into components......

Yes, it's right. it's a dispersion.

Reflection occurs when the obstacle is quite lager than the wavelength of light and which maintain the same incident a angle and reflected angle value.But in scattering no such equality in not maintained, where the light spread out to all possible direction depending on how small size of the obstacle size. I think so about refection and scattering, but what is the difference between diffraction and scattering?

for reflection angle of incidence is equal to angle of reflection.
for scattering angle of reflection is different from angle of incidence.
scattering depends on wavelength of light and size of particles from which light scatters.
from reflection we don't get much information about structure of matter but scatterring is widely used in spectroscopy .
