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).

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

It is fun to play with prism. (light trace and intensity due to refraction)
