The wavenumber and (b) the wavelength of the radiation used by an fm radio transmitter broadcasting at 92. 0 mhz will be 31.25 *
and 0.032 *
m respectively
Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.
Wavenumber, also called wave number, a unit of frequency, often used in atomic, molecular, and nuclear spectroscopy, equal to the true frequency divided by the speed of the wave and thus equal to the number of waves in a unit distance.
wavelength = ?
frequency = 92 m Hz = 92 *
Hz
speed of light = 3 *
m/s
speed of light = frequency * wavelength
wavelength = speed of light / frequency
= 3 *
/ 92 *
= 0.032 *
m
wavenumber = 1 / wavelength
= 1 / 0.032 *
m
= 31.25 *

The answer would be 46.482 because you multiply 18.3 by 2.54 because for every inch you get 2.54 centimeters
Answer: This type of questions are called probing questions. The correct option is D.
Explanation:
Probing questions are the type of questions that are asked to investigate an ongoing event. It helps the investigator to know more about what is happening and how to obtain conclusive decisions through the personal opinions of the respondent . For example from the question, Liza wanted to know more about the project updates which was held in the weekly meetings. She asked her employees questions like:
- Why were you late meeting your last deadline?
-Were there external factors that delayed your work?
-Did other coworkers get their part of the assignment to you on time?
- Do you need more help from me?".
PE = mass * height * 9.81
PE = 142 * 25 * 9.81
PE = 34825.5 J
