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. |
