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

of an electronic wave packet in the unifonn field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more then one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination ofparameters of such packet by powerful laser pulse scattered with is discussed. The motion of one-electron wave packet in the nonuniform

What does tradition mean to you? In the Sound of Waves tradition is valued greatly. The Sound of Waves by Yukio Mishima deals with two young adults who fall in love with each other and have to deal with the gossip of the town. Mishima uses characterization to develop the theme “Tradition will always be valued more than modernization” throughout the Sound of Waves. Mishima uses the relationships of the townspeople to represent the importance of tradition on the island. “Like this I should be able

Investigating Snells Law Investigating Snell’s Law Research Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where

story. The tranquil diction used by Yukio Mishima in The Sound of Waves is very important to the calm island setting used in the story. The author’s smooth word choice complements the burgeoning love between Shinji and Hatsue‚ the two main characters. Mishima’s style also accentuates many instances of situational irony between the two young lovers and is only one of the many elements he uses in his composition. The Sound of Waves is a love story about Shinji and Hatsue and how they conquer the
