SUMMARY

The discussion centers on calculating wavelength from frequency, specifically using a frequency of 99 MHz. The formula for wavelength is established as wavelength = velocity of light / frequency. Given that the speed of light is approximately 3 x 10^8 m/s, the calculation simplifies to 300 / frequency in MHz. Therefore, for 99 MHz, the wavelength is calculated to be approximately 3.03 meters.

PREREQUISITES
  • Understanding of the relationship between frequency and wavelength
  • Knowledge of the speed of light (3 x 10^8 m/s)
  • Familiarity with basic physics formulas
  • Ability to perform unit conversions (MHz to Hz)
NEXT STEPS
  • Study the derivation of the wavelength formula from wave physics
  • Learn about electromagnetic spectrum and its applications
  • Explore the implications of wavelength in communication technologies
  • Investigate the effects of frequency on signal propagation
USEFUL FOR

This discussion is beneficial for physics students, telecommunications engineers, and anyone interested in understanding wave properties and their calculations.

I don't remember the question exactly because I saw it in my final exam and I'm confused and don't know how to solve it exactly, so here's the question:
99 MHZ (99000000 HZ) frequency is produced to a 60 m base, find the wavelength.
They didn't mention neither the velocity nor the time, and I know to find the time is to put 1/frequency. And does the velocity has the speed of light which is 3 x 10^8. Formula: V=wavelength x frequency
As I told you I don't remember the question exactly but it looks like what I wrote above.
I'm waiting for an answer as soon as possible.
Thanks!

What does that mean?
 
likewise, don't know what produced to a 60 m base means, doesn't make sense

wavelength is simply velocity of light / freq
cutting off a lot of 0000's ... 300 / freq (in MHz) = wavelength in metres

so 300 / 99 = 3.03m
