Beat Frequency: Find Frequency with Wavelength of 3.141m & 3.135m

Click For Summary
SUMMARY

The beat frequency for radio waves with wavelengths of 3.141m and 3.135m can be calculated using the formula Fb = |f1 - f2|. To find the frequencies, one must first determine the speed of electromagnetic waves, which is the speed of light at approximately 299,792,458 meters per second. Using the relationship between speed, frequency, and wavelength (v = fλ), the frequencies can be derived as f1 = c/λ1 and f2 = c/λ2. This results in a beat frequency of approximately 0.0047 Hz.

PREREQUISITES
  • Understanding of electromagnetic wave properties
  • Knowledge of the speed of light (approximately 299,792,458 m/s)
  • Familiarity with the relationship between frequency, wavelength, and speed (v = fλ)
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Learn how to calculate frequency from wavelength using the formula f = c/λ
  • Explore the concept of beat frequency in wave physics
  • Study the properties of electromagnetic waves and their applications
  • Investigate the behavior of radio waves in different mediums
USEFUL FOR

Students in physics, educators teaching wave mechanics, and anyone interested in understanding the principles of electromagnetic waves and beat frequencies.

Homework Statement



What would be the beat frequency if radio waves of wavelength 3.141m and 3.135 are mixed?

The Attempt at a Solution



I need frequency of wave1 and wave2, because Fb=|f1-f2|
But i don't have nothing but wavelength...
Any hints?
 
Physics news on Phys.org
Can you work out the frequency?

HINT: At what speed do radio waves travel?
 
I have no idea... Where can I find that?

Another hint: Radio waves are electromagnetic waves. At what speed do all EM waves travel at?
 
Iw as trying but no idea at all...
 
What speed does light travel at?
