1)
When the angle of the prism changes from 50
0
to 70
0
, then what happens to the minimum deviation ?
Increased by 20
0
No change
Decrease
Increase
2)
If the velocity of incident ray is less than the velocity of transmitted ray through a medium. Then angle of refraction is ……?
Greater than angle of incidence.
Less than angle of incident.
Equal to angle of incident.
There is no angle of refraction.
3)
What type of eye piece is used in the spectrometer given in the simulator?
Ramsden’s eye piece
Kellner eye piece
Symmetrical (or Plossl) eye piece.
Orthoscopic eye piece.
4)
A ray of the light travels from medium of refractive index N1 to a medium of refractive index N2 , if angle of incidents is ‘i’ and angle of refraction is ‘r’ then sin(i)/sin(r) = ?
