All it the question says is that AM modulation operates at 1 AM = 1 KHz
and 800 AM = 800 KHz. the questions says to calculate the wavelength of radio station broadcasting at 820 AM
now i know that frequency is 820 KHz but i don't know what velocity it travels at so how do i calculate the wavelength from that

You should know the speed it travels at.

What speed do all electromagnetic waves travel at?
 
  • #3
i don't know its not given in the book..
 
  • #4
looking it up on the internet it says 3.0 x 10^8 m/s is that correct
 
  • #5
yes, that's the speed of light and it's the speed at which all em waves
 

Related to Enough information? (WaveLength Question)

1. Is there such a thing as "enough" information?

The concept of "enough" information is subjective and can vary depending on the context. In some cases, having more information can lead to better understanding and decision making, while in others, having too much information can be overwhelming and unnecessary. It is important to consider the purpose and goal of gathering information before determining if it is enough.

2. How do we know if we have gathered enough information?

The answer to this question differs depending on the specific situation. Generally, having a clear and defined goal or objective can help determine if the information gathered is sufficient. Additionally, seeking feedback and input from others can provide valuable insights on whether more information is needed.

3. Can we ever have too much information?

Yes, it is possible to have too much information. When there is an overwhelming amount of data, it can be challenging to process and make use of it effectively. This can lead to decision paralysis and hinder progress. It is important to prioritize and filter information to avoid information overload.

4. How does the amount of information affect decision making?

The amount of information can significantly impact decision making. In some cases, having more information can lead to better decisions as it provides a more comprehensive understanding of the situation. However, too much information can also lead to decision fatigue and make it difficult to reach a conclusion. Finding a balance and focusing on relevant information is crucial for effective decision making.

5. Is it possible to make decisions without having all the information?

Yes, it is possible to make decisions without having all the information. In some cases, a quick decision is necessary, and gathering all the information may not be feasible. In these situations, it is crucial to assess the available information and make the best decision based on the current knowledge and understanding. However, it is essential to continue gathering information and reassessing the decision as more information becomes available.
