The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
Answer:
Terrestrial planets are formed from rocks which are also known as telluric planet. They are composed primarily of silicate rocks or metals. Then, the Jovian planets are known as gas planets. Terrestrial planets include Mercury, Venus, Earth, and Mars while the Jovian planets are Jupiter, Saturn, Uranus, and Neptune.
Explanation:
By observing how seismic waves are absorbed and refracted, scientist have been able to work out where the properties of the earth change dramatically. our understanding of the internal structures of the earth and the size of its core is based on these observations.
basically:
size of core
structure of the earth I.e. the layers of the earth
and I think the last one is how the internal structure is changing? not sure on the last one but its still a solid guess.
