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 90o.
The set of rectangular axes obeying the Newton's laws of motion and used to describe the position of a particle or an event are known as inertial frames of reference.
