The phenomenon of total internal reflection occurs when a ray of light travels from

If \( I = 16 \, \text{A} \), electron density \( n = 5 \times 10^{23} \, \text{m}^{-3} \), and \( A = 1 \times 10^{-7} \, \text{m}^2 \), find the drift velocity.

A plane wave front is incident on a thin prism, thin convex lens and a concave mirror separately. The wave front(s) emerging out from the
