Hope it helps...

Answer 2

Fill in the blanks


(i) Image formed by a plane mirror is erect, virtual and same size as that of the object and is present at the same distance behind the mirror


(ii) Second law of refraction is also known as snells law

(iii) Light ray falls normally on plane mirror; the angle of reflection will be zero as the angle between the incidence and the normal is zero


(iv) For bending away from the normal, light should travel from denser medium to rarer medium.
