describe the behavior of the waves in the following situations:waves strike a surface or boundary.?

Answer 1

Upon reaching a boundary between two mediums, the usual two behaviors will occur in waves.

1. A portion of the energy carried by the incident pulse is reflected and returns. The disturbance which returns after bouncing off the boundary is known as the reflected pulse (reflection).

2. A portion of the energy carried by the incident pulse is transmitted into the next medium. The disturbance which continues moving into the new medium is known as the transmitted pulse.

The boundary behavior of waves can be summarized by the following principles:

1. the wave speed is always greatest in the least dense medium;

2. the wavelength is always greatest in the least dense medium;

3. the frequency of a wave is not altered by crossing a boundary;

4. the reflected pulse becomes inverted when a wave in a less dense medium is heading towards a boundary with a more dense medium; and,

5. the amplitude of the incident pulse is always greater than the amplitude of the reflected pulse.

Answer 2

Hi. They reflect.
