SUMMARY

The discussion focuses on calculating the wavelength of waves transitioning between different mediums, specifically addressing a scenario with an initial speed of 150 m/s and a frequency of 75 Hz in the first medium, and a reduced speed of 96 m/s in the second medium. It is established that frequency remains constant during this transition, which is crucial for determining the wavelength. The formula for wavelength is derived from the relationship: wavelength = speed / frequency, allowing for the calculation of the new wavelength in the second medium.

PREREQUISITES
  • Understanding of wave properties, including speed, frequency, and wavelength.
  • Familiarity with Snell's Law for calculating angles of incidence and refraction.
  • Basic knowledge of physics principles related to wave behavior in different mediums.
  • Ability to perform calculations involving ratios and algebraic manipulation.
NEXT STEPS
  • Study the application of Snell's Law in various mediums.
  • Learn how to calculate wavelength using the formula: wavelength = speed / frequency.
  • Explore the concept of wave speed variations in different materials.
  • Investigate the implications of wave frequency constancy during medium transitions.
USEFUL FOR

Physics students, educators, and anyone interested in understanding wave behavior across different mediums, particularly in the context of optics and acoustics.

Please help!

In my physics, I need to find the wavelengths of the waves from a source in a different medium.

In the first medium, my angle of incidence is 35 degrees and with a speed of 150m/s and a frequency of 75Hz. In the different medium the speed has dropped to 96m/s. I know the angle of refraction will be smaller. But how do I figure that out as well as the frequency in order to determine the wavelength?

i guess what i really want to know is if frequency changes as it crosses a medium,
 
Nope, frequency is the one constant.
