- AThickness of the medium
- BRefractive index of the medium
- CAngle of incidence
- ✓All the above
Lateral displacement due to a slab is given by $\delta=\text{t}(\mu−1)$; where t is thickness of the medium and $\mu $ is refractive index of medium.

Reason: In a reverse bias condition the current is small but is more sensitive to changes in incident light intensity

$A.$ By changing the magnitude of the magnetic field within the coil.
$B.$ By changing the area of coil within the magnetic field.
$C.$ By changing the angle between the direction of magnetic field and the plane of the coil.
$D.$ By reversing the magnetic field direction abruptly without changing its magnitude.
