1. Reflection

   • Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

2. Refraction

   • refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

3. transmission

   • transmission of light is the moving of electromagnetic waves
