Wave Revision Flashcards
longitudinal wave
Oscillations are parallel to direction of energy transfer/ wave motion.
transverse wave
Oscillations are at 90° to direction of energy transfer/ wave motion.
Matter wave
A wave travelling through matter
Non-Matter wave
Can propagate through a vacuum

specular reflection
a reflection produced by a smooth surface in which parallel light rays are reflected in parallel
diffuse reflection
Reflection that occurs when parallel rays of light hit a rough surface and all reflect at different angles
Incident ray parallel to principal axis
Will reflect through focal point
Incident ray through focal point
Will reflect parallel tp principal axis
