1)
When we introduce a liquid drop between lens and glass plate, the radius of rings
reduce by a factor µ
reduce by a factor µ½
increase by a factor µ
increase by a factor µ½
2)
When we incident the light normally,what happens to angle of incidence(i) and angle of reflection(r)
i=90°,r=0°
i>r
i=r=90°
i=r=0°
3)
The light is allowed to fall obliquely on glass plate,then
diameter of rings decreases
no change
diameter of rings increases
no ring is observed
4)
Gas inside sodium vapour lamp
Helium
No gas
Mercury
Neon
5)
Which among the following causes the ring to deform from its circular shape?
The surface of lens and glass plate is clean.
Constant thickness of air film.
The surface of the ring may not be a part of perfect sphere.
Glass plate is optically flat.
