What are waves?

Particles that transfer energy from one place to another

Standing waves

-maximum displacement greater than progressive waves


- doesn't move at all at some points


- fixed at some points and maximum displacement at other points


-formed by two progressive waves going in two different directions with the same wavelength and frequency.

Graded index

- signals follow curved path


-gradual change in refractive index


-follow same path


-signals arrive at same time


-follow longer paths travel faster


-lower refractive index- cladding signals travel faster.
