Seismic Waves What are seismic waves? Seismic waves are the waves of energy caused by breaking of rock within the earth or an explosion. These waves are the energy that travels through the earth and is recorded on seismographs. There are many different types of these waves‚ but the two main ones are the body waves that usually travel though in inner layer of the earth‚ and the surface waves that only move around the surface of the planet. Body waves travel through the inner layer of the earth

Electromagnetic Waves Although you might not know it you’re constantly surrounded by thousands of electromagnetic waves every day. Sunlight and x-rays are only two types of electromagnetic waves‚ other types are: radio wave‚ infrared rays‚ ultra-violet rays and gamma rays Nature of an electromagnetic wave Electric and magnetic fields are not made up of matter. An electromagnetic wave consists of an electric and magnetic field and doesn’t need a medium to exist. They are the regions through

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

1.0 What Causes the Tides Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the earth and the moon. Tides are the cyclic rising and falling of earth’s ocean surface caused by the tidal forces of the moon and the sun acting on the earth . Tides cause changes in the depth of the sea and produce oscillating currents known as tidal streams‚ making prediction of tides important for coastal navigation. The strip of seashore

seven different waves. The waves are in the order of how big the wavelength is and its frequency‚ from the biggest to the smallest: Radio waves‚ Micro waves‚ Infrared‚ Visible light‚ Ultra Violet‚ X-rays and Gamma rays. Each of them has their own special use in everyday life. For example‚ to turn on a TV you need to use Radio waves‚ to heat your food you use Microwaves and X-rays are used to look into people’s bodies. Some waves‚ like Radio waves can be as big as a building or waves like Gamma rays
