Define angular frequency, wave number and wave vector.

Text Solution

Verified by Experts

(i) The number of cycles (or revolutions) per unit time is called angular frequency. Angular frequency `omega =(2pi)/(T)= 2pi f`, (unit is redians/second).
Wave number, `l=(2pi)/(lambda)` (units is radians/ meter)
