Explanation / Answer

13) When we view nearby objects ,the ciliary muscle are tensed to give the lensmore curvature,and the lens shortens its focal length then more refraction.The process of changing the shape of the lens and hence adjusting its focal length is called as accomdation

so the answer is True

14) True

15) for plane mirror,virtual image is formed and image distance = object distance

So the answer is

E)   
at the same distance behind the mirror as the object is in front of the mirror.

16) reflection from rough surfaces are called as diffuse reflections

So the answer is False
