What is regular reflection

When rays of light falls on smooth surface,they are reflected parallely

So we are able to clearly see reflection


Rays of light on mirror is regular reflection because mirror is smooth



What is irregular reflection or diffused reflection

When rays of light fall on rough or irregular surface,the light reflects on different directions

They are not parallel

Hence reflection is not clear


We are not able to see our image on plastic clearly because it is not as smooth as mirror
