NSTSE sample question paper

I need the NSTSE sample question paper, is there any buddy to provide me the same?????????????

[Kiran Chandar]

As per your request here I am sharing the NSTSE sample question paper:

A ray of light in a liquid of refractive index 1.6, approaches
the boundary surface between the liquid and air at an
angle of incidence i where sini = 0.7.
Which of the following
statements is true about the behaviour of the light?
(A)It is impossible to predict the behaviour of the light t:ay
onthe basis of the information supplied
(B)The sine of the angle of refraction of the emergent ray will
be less than 0. 7
(C)The ray will be internally reflected
(D) The sine of the angle of refraction of the emergent ray will
be
greater than 0.7.


Which of the following statements is not true?
(A)
In Fresnel diffraction, both source and screen are near the
aperture.
(B)
In
Fresnel diffraction,
ray from
the source and ray to the
screen are considered to be parallel.
(C)
In Fraunhoffer diffraction, both light source and screen are
very far from the aperture.
(D)
In Fratmhoffer diffraction, rays incident on the aperture and
leaving the aperture are parallel.
