PhysicsHardsingle choice

The critical angle of a medium for a specific wavelength, if the medium has relative permittivity $3$ and relative permeability $\frac{4}{3}$ for this wavelength, will be:

Options:

Answer:

Solution:

$V = \frac{1}{\sqrt{μ ε}}$
$n = \sqrt{μ_{r} ε_{r}} = 2$
$s i n i_{c} = \frac{1}{n} = \frac{1}{2}$
$i_{c} = 30 °$
