    Convert Wavelength

SUMMARY

The discussion centers on calculating the frequency of sound emitted by bats with a wavelength of 3.5mm in air at 30 degrees Celsius. The speed of sound in air is calculated using the formula V = 331.4 + 0.6 * Temp.C, resulting in a speed of 349.4 m/s. The frequency is then determined using the equation V = wavelength * frequency, leading to a frequency of approximately 99829.6 Hz. It is confirmed that converting the wavelength from millimeters to meters is necessary for accurate calculations.

PREREQUISITES
  • Understanding of sound wave properties
  • Familiarity with the speed of sound formula
  • Knowledge of unit conversion (millimeters to meters)
  • Basic algebra for solving equations
NEXT STEPS
  • Study the relationship between wavelength, frequency, and speed of sound
  • Learn about temperature's effect on sound speed in different mediums
  • Explore sound wave properties in various environments
  • Investigate applications of bat echolocation in biology and technology
USEFUL FOR

Students studying physics, acoustics researchers, and anyone interested in the principles of sound wave behavior in different mediums.

Homework Statement



The sound emitted by bats has a wavelength of 3.5mm. What is the sound's frequency in air? Assume that the bat is flying through air with a temperature of 30 degrees C.

Homework Equations



V=331.4 + 0.6*Temp.C
V=wavelength*frequency

The Attempt at a Solution



V= 331.4 + 0.6(30)
V=349.4m/s

V=wavelength*frequency

349.7m/s=0.0035*f
f=99829.6hz

The only thing I'm not sure about is did I need to change the 3.5mm to .0035m?
