The essential characteristic that changes is the speed of the wave. The wavelength also changes.
Amplitude and polarization can change. What does not change is the frequency.
A sharp change in temperature or air mass characteristics is considered a boundary between two different fronts. This boundary is known as a "frontal boundary" and often leads to distinct weather changes and patterns.
it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.
it is speed
The International Date Line is where the date changes, not the boundary between night and day. There is no name for that boundary, because it always moves.
The direction of the wave changes if its speed is different in the two media.
the way the altitude changes the temperature changes
What changes in earth's surface that happen at a convergent boundary with those happen at a divergent boundary?
When a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant. If the beam of light is not orthogonal (or rather normal) to the boundary, the change in wavelength results in a change in the direction of the beam. This change of direction is known as refraction. Which basically means each color is on a Different "wavelength" which causes it to go in a slightly different angel after it hits a refraction-able object
A dynamic characteristic refers to a feature or attribute that changes or varies over time in response to different factors or conditions. It implies that the characteristic is not fixed but rather evolves or adapts based on its environment or inputs.
The boundary between Korea and Manchuria, also known as the Korean-Manchurian border, was primarily established along the Yalu River. This river served as a natural boundary dividing the two regions. The border has gone through some changes over time due to various historical events and political agreements between the two countries.
The variable changes.
The Gutenberg Discontinuity, is the boundary, as detected by changes in seismic waves, between the Earth's lower mantle and the outer core about 1800 miles below the surface. It is also called the core-mantle boundary.
