Total internal reflection, Physics

Assignment Help:

Light is shined into a glass rod. To guarantee the total internal reflection (TIR) happens to all the possible rays, what is the minimum index of refraction n for the glass?

Hint: To make sure all rays TIR inside the rod, you just need to consider an extreme case, i.e., the incident angle q₁ (on the top surface of glass rod) equals to 90^o.
