Question

A laser pen is initially immersed in water (refractive index n₂) and fires the light beam shown in the figure. The pen begins to move toward the surface, always pointing at the same point on the interface between water and air and always maintaining the same horizontal distance x from that point. Given that air has refractive index n₁ and defining the ratio r by r = n₂/n₁, the value y limit of total internal reflection is:

√(1-r²)
x² √(1-r²)
x² √(1-1/r²)
x² √(1/r²-1)
x √(1/r²-1)
x² √(r²-1)
x √(1-r²)
√(r²-1)
√(1/r²-1)
x √(1-1/r²)
√(1-1/r²)
x √(r²-1)
