There is a mistak

Answer :

(a) The mistake in the above figure is that the direction of the propagation of the ray is wrong. In the diagram it is shown that the ray is propagating in the direction of reflected ray to the direction of the incident ray but the direction of propagation should be from the direction of incident ray to the direction of reflected as shown in the corrected figure below: -


(b) The mistake in the above figure is that it is not obeying the laws of reflection. It is not following the law that the angle of reflection is equal to the angle of incidence as in the above figure both the angles are not equal. Hence, the corrected figure with equal angle of incidence and reflection is as shown below: -



(c) The mistake in the above figure is the same as that of the previous one that it is not obeying the laws of reflection. It is not following the law that the angle of reflection is equal to the angle of incidence as in the above figure both the angles are not equal. Hence, the corrected figure with equal angle of incidence and reflection is as shown below: -
