Chapter 11, Problem 6STP

To determine

To Choose: The correct option.

Answer to Problem 6STP

The correct option is (C).

Explanation of Solution

Introduction:

Interference is called the superposition of two waves forming the resulting one that is greater or less or equal in amplitude.

The speed of electromagnetic waves is constant which can’t be altered for communication purpose. Amplitude is such a parameter which determines the energy carried by the signal. The strength of the signal is affected by amplitude.

So, the options (A),(B) and (D) are incorrect.

The wave frequency is so defined that they don't interfere during transmission and cause distortion. Thus, the correct option is (C).

Conclusion:

Hence, option (C) has explained accurately the given phenomenon.
