Title: Reflection/Refraction in 3D (intensity/ p-s wave)
Post by: Fu-Kwun Hwang on March 20, 2010, 12:58:49 pm
This applet show reflection and refraction in 3D to illustrate
incident ray/reflected ray and refracted ray all lie on the same plane.

The reflected angle is the same as incident angle.
The refracted angle is determined by Snell's law $n_1 \sin\theta_1=n_2 \sin\theta_2$

The intensity for reflected wave and refracted wave were calculated for p-wave or s-wave.

The check box labeled "E" is used to toggle display of Electric field.
The electric field for p-wave and s-wave are perpendicular to each other.

At Browster angle (\theta=0.98 for default case), the p-wave dispappear. (Please DO try it !)

You can use mouse drag and drop to change the view point (viewing angle/rotate the 3D system).
