1)
The degree to which a substance bends light is known as the
Resolution
Numerical aperture
Refractive index
Magnification
2)
When light passes through air to a medium with a great refractive index (i.e., glass), what happens to the light?
The velocity of light decreases and it bends away from the normal
The velocity of light decreases and it bends toward the normal
The velocity of light increases and it bends away form the normal
The velocity of light increases and it bends toward the normal
3)
In an optical fiber, the inner core is
the cladding
4)
Wave propagation constant 'k' is
K = 2π/λ
K = 2πλ
K = 2λ/π
K = (πλ)2
5)
Quantum efficiency η is expressed as
η = no. of e-h pairs generated/no. of incident photon
η = no. of incident photon/no. of e-h pairs generated
η = no. of e-h pairs generated * no. of incident photons
None of the above
6)

1.65
2.85
1.45
