Two radio waves are used in the operation of a cellular telephone. to receive a call, the phone detects the wave emitted at one frequency by the transmitting station or base unit. to send your message to the base unit, your phone emits its own wave at a different frequency. the difference between these two frequencies is fixed for all channels of cell phone operation. suppose the wavelength of the wave emitted by the base unit is 0.34394 m and the wavelength of the wave emitted by the phone is 0.36140 m. using a value of 2.9979 108 m/s for the speed of light, determine the difference between the two frequencies used in the operation of a cell phone.

Explanation:

The frequency of an electromagnetic wave is given by:

where

is the speed of light

is the wavelength of the wave

For the first wave,

so the corresponding frequency is

For the second wave,

so the corresponding frequency is

So the difference between the two frequencies is

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
