Pilots often use waves of about 2.340m to communicate. what is the frequency of the wave ? why?

All of the various light waves move with the same speed, a value

abbreviated (c) equal to 3.00 × 108 m/s. The frequency ([1]) that light waves pass a given point is

measured in waves/second or simply ‘per second’ (1/s).

the frequency of the wave f = (3.00 × 10^8 m/s)/ 2.340 m

f = 1.28x10^8 Hz

explanation: no but i do not usually comment
