Rotational speed would increase...
v = omega . r
which means it's directly proportional to radius...
Answer:
(d) 16°
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 25.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (glass, n=1.5)
is the refractive index of the incidence medium (air, n=1)
Hence,
Angle of refraction =
= 16°
