Imagine the door to a theatre is opened and you are standing outside. how is it possible that you can hear the sound of the movie or play even if you cannot see the screen or stage ?
a) reflection only happens with sound waves not waves of light so the sound waves bounce out to your ears.
b) the sound waves refract as they move from one medium to another
c) the darkness in the theatre absorbed light but not sound so you can hear
d) the sound waves diffract much more than the light waves so try bend and spread as they move through the doorway.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
