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

Estimate the Speed of Light inside a Transparent Plastic Block 1. Preparation: a) Read about refraction of waves and Snell’s Law. b) Find the relation between the refractive index of a medium and the speed of light in that medium. c) Read about total internal reflection; especially the definition of the “critical angle of incidence”. 2. Using the special apparatus provided‚ measure the angles of refraction corresponding to a wide range of angles of incidence. Remember‚ the angles of incidence and refraction

Free Light Refraction Electromagnetic radiation
Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium‚ the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon‚ When light travels from air into water‚ it slows down‚ causing it to change direction slightly. This

curvature C. Focus :The principal focus is defined as the point on the principal axis where the light rays traveling parallel to the principal axis after reflection actually meet (for a concave mirror) or appear to meet (for a convex mirror). Pole : The pole is defined as the geometric center of the curved mirror. Rules of Reflection for Curved Mirrors 1. Any light ray traveling parallel to the principal axis is reflected by the curved mirror through the principal focus. It either actually

This method is based on total external reflectivity. Using this method we can calculate the thickness of the film electron density profile of the material and roughness of the film surface. After a short introduction of Fresnel’s reflectivity‚ the Parratt formulation is used for

refractive index and the ray should hit the center of the glass circle‚ so to check that the ray hits the center of the glass circle‚ we placed a wood block at the angle of reflection to see if the angle of reflection is the same as the angle of incidence‚ because we know that the angle of incidence is equal to the angle of reflection. Another thing which makes it easier to hit the center of the glass circle is by placing a paper on the flat side of the circle and see if the ray hits the center of the
