the light we see as a rainbow. The light hits the raindrop and is dispersed or split like going through a prism. Then‚ the separated colors are reflected off the backside of the drop and then exit where they are refracted again‚ as the index of refraction index changes between water and air. Each raindrop contributes only one color to the rainbow that you see. In looking at a rainbow‚ you are seeing the collective picture made by millions of raindrops. (figure 1) figure 1. The raindrops that

Refraction- deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different Medium- a substance regarded as the means of transmission of a force

NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

The wave model can be used to explain how current technologies transfer information * describe the energy transformations required in one of the following: mobile telephone‚ fax/ modem‚ radio and television Energy transmission in mobile telephone: sound wave energy (input sound) -> electrical (in transmitting phone) – > radio wave (transmit signal) -> electrical (in receiving phone) -> sound (output sound) * describe waves as a transfer of energy disturbance
Premium Light Electromagnetic radiation Wavelength
Reflection Experiment Background Information The law of reflection states that the angle of incidence will be equal to the angle of reflection. I.e. the angle that the light strikes the reflective surface at will be the same as the angle that it leaves it at. Aim To investigate the law of reflection and evaluate its accuracy. Hypothesis The law of reflection will be correct. Apparatus and Materials Light Box Mirror Protractor Blank Paper Safety This experiment is

The ninth and last step is to record (on a piece of paper) the three different angles of refraction with its corresponding laser wavelengths on a data

bands of resistant and weak rock which when in contact with the discordant waves makes the soft rock erode much quicker to form bays. The Bay is made bigger by the spray from the waves also causes chemical weathering on the cliffs of the soft rock. Refraction of waves from the headland‚ these waves drift inwards towards the bay ‚ these waves have more of an effect on the weaker rock so it erodes rapidly. Headlands are formed when the soft rock has retreated to form a bay which leaves a headland sticking
