SUMMARY

The speed of a longitudinal wave with a frequency of 20.0 Hz and a wavelength of 0.4 m is calculated using the formula v = wavelength × frequency. Substituting the given values, v = 0.4 m × 20.0 Hz results in a wave speed of 8 m/s. This calculation is confirmed as correct by participants in the discussion.

PREREQUISITES
  • Understanding of wave properties, specifically frequency and wavelength
  • Familiarity with the formula for wave speed (v = wavelength × frequency)
  • Basic knowledge of longitudinal waves
  • Ability to perform simple arithmetic calculations
NEXT STEPS
  • Study the characteristics of longitudinal waves in more detail
  • Explore the relationship between wave speed, frequency, and wavelength in different mediums
  • Learn about wave interference and its effects on wave speed
  • Investigate applications of wave speed calculations in real-world scenarios
USEFUL FOR

Students studying physics, educators teaching wave mechanics, and anyone interested in understanding wave behavior and calculations.

1. A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coil spring. if the distance between successive compressions is 0.4m, what is the speed of the wave?


2. v= wavelength times frequency



3. v= wavelength times frequency
= 0.4 * (20)
= 8 m/s ------ I'm not sure if this is right.

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
