Chapter 14.3, Problem 31SSC

To determine

The characteristics that remains unchanged when a wave changes its mediums.

Answer to Problem 31SSC

Characteristics like frequency, amplitude, wavelength, velocity and direction may change when entered into different medium.

Explanation of Solution

When a wave changes mediums, velocity and wavelength change according to the medium. These two characteristics depend on the properties of the medium itself.

Frequency of the wave remains same as it not dependent on the medium in which the wave is travelling.

Conclusion:

Velocity and wavelength changes whereas frequency remains unchanged according the medium.
