1)
When we introduce a liquid drop between lens and glass plate, the radius of rings
reduce by a factor µ
increase by a factor µ
increase by a factor µ½
reduce 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=90°
i=r=0°
i>r
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
No gas
Neon
Helium
Mercury
5)
Which among the following causes the ring to deform from its circular shape?
The surface of lens and glass plate is clean.
Glass plate is optically flat.
The surface of the ring may not be a part of perfect sphere.
Constant thickness of air film.
