Test your understanding of this lesson Refractive index:-

1)
If angle of incidence be y in medium A and that of refraction be x in medium B , the refractive index of 'B' with respect to A is :
  • \sin y/\sin x
  • \sin x/\sin y
  • \sin^{2} x/\sin y
  • \sin x/\sin^{2} y
2)
If the velocity of light in air and glass be \(3*10^{8}\) m/s and \(2*10^{8}\) m/s respectively , absolute refractive index of glass is :
  • \(\frac{2}{3}\)
  • 1.5
  • 1
  • \(6*10^{16}\)
3)
Which one has greatest absolute refractive index?
  • Water
  • Air
  • Glass
  • Vacuum
4)
When Refractive index of a medium increases :
  • Velocity of light remains same in the medium
  • Velocity of light increases in the medium
  • Velocity of light decreases in the medium
  • Velocity of light initially increases , then decreases in the medium
5)
Absolute refraction index of vacuum is :
  • 0
  • 1
  • 1.5
  • 0.5
