How often waves happen?
were are waves happen at
When did Alpha Waves happen?
Alpha Waves happened in 1990.
Why can AM broadcasts be heard for greater distances under certain conditions?
You can hear AM stations farther away more at night due to a condition known as SKIP, or Skywave Propagation. The propagation of AM radio waves changes drastically from daytime to nighttime. This change in AM radio propagation occurs at sunset due to radical shifts in the ionospheric layers, which persist throughout the night. During daytime hours when ionospheric reflection does not occur to any great degree, AM signals travel principally by conduction over the surface of the earth. A condition known as "groundwave" propagation. Useful daytime AM service is generally limited to a radius of no more than about 100 miles, even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called "skywave" propagation. Basically the AM signal bounces off the ionosphere back to the earth rather than traveling in a direct line. This bounce allows the signal to be heard over vast distances. Amateur radio operators call this talking skip.
Where does interference of waves occurs?
It can happen any place where two waves meet. This is usually most relevant when both waves have the same frequency.
Kind of wave released during an wave?
Earthquake waves are called seismic waves.
How are waves made in the day time?
Waves are made in the daytime the same way they are made at nighttime. Primarily by wind, and occasionally by seismic shocks.

Why do waves happwen?
waves happen because it drives the ocean and its happen not happwen
When did Alpha Waves happen?

What seismic waves?
Seismic waves are vibrations that travel through the Earth carrying the energy released during earthquakes. == Seismic waves are waves that are a result of earthquake activity in the earth. There are body and surface waves. Body waves happen inside the earth and are called P (longitudinal) and S (transverse) waves. Surface waves happen on the Earth's surface and are called Rayleigh and Love waves. P-waves (primary waves) go first, compress and expand the earth, and are faster. S-waves (secondary waves) go second, move the ground up and down or side to side, and are not as fast as P waves.

What is the difference between a tsunami and seismic waves?
tsunami's happen underwater and seismic waves happen on land or underground.
What is the range of a periscope on a submarine?
There is no set range limit for a periscope; it's affected by many factors, weather conditions playing a large part. In addition to weather, the height of the periscope above the water, sea state (height of the waves), target profile (large, small, low or high in the water), daytime or nighttime, all affect a periscope's actual range.
What will happen to a base-isolated building when seismic waves strike the building during earthquake?
it will not break it will just stand because it is build to be strong.
