α = \frac{cos (θ_{t})}{cos (θ_{i})}

$alpha = cos( theta_t )/cos( theta_i )$

This equation calculates $α$ $alpha$ (using $θ_{i}$ $theta_i$ and $θ_{t}$ $theta_t$ ), used in calculating the amplitudes of EM waves striking an interface. For more information and context on this equation, please see the EM waves at the interface of two insulators.

$θ_{i}$ $theta_i$ is the angle between the incident wave and the normal of the interface.
$θ_{t}$ $theta_t$ is the angle between the transmitted wave and the normal of the interface. $θ_{t}$ $theta_t$ is on opposite sides of the interface and the normal as $θ_{i}$ $theta_i$ .

For more information on $θ_{i}$ $theta_i$ and $θ_{t}$ $theta_t$ , please see the Angles of Reflection and Refraction.
