The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.
spherical waves at far distance act like plane wave
The difference between the arrival times increases as the distance from an earthquake epicentre increases as S-waves travel more slowly than P-waves so the greater the distance the further they lag behind.
Yes the two waves are different.
hi
Radio waves hit all obstacles the same, but the waves will differ in the distance of the wave and/or the object from the transmitter.

4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
surface waves
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
Yes. Sound waves have different frequencies which cause them to be louder/softer/higher/lower.Light waves have different frequencies too. The shorter the distance between the wavelenghts the darker the color. White light (the normal light the sun gives) is all of the colors together
The wave length. This is also correct if you are referring to the distance between the trough of two waves.
Sound waves.
Infrared and X-ray are alike, in that both of them are electromagnetic waves, albeit different. Electromagnetic waves are "a phenomenon that takes the form of self-propagating waves in vacuum or in matter." (Wikipedia article) They are both parts of the Electromagnetic spectrum (Wikipedia article) The difference between the different wave of the spectrum is their wavelength ."The distance over which the waves shape repeats." (Wikipedia article)
they are different because these waves can travel through empty space
Radio waves ARE electromagnetic waves.
