investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method: 1. The semicircular

called specular or regular reflection. The laws of reflection are as follows: The incident ray‚ the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. he reflected ray and the incident ray are on the opposite sides of the normal. These three laws can all be derived from the reflection equation

is observed with surface waves in bodies of water. Reflection is observed with many types of electromagnetic wave‚ besides visible light. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common

Dawn is an opposite character relating to Ray and Sylvie‚ just as they have lost their daughter‚ Dawn has lost her parents. This meeting between Ray and Dawn also provides the audience with another side to Ruby that was not previously known- “Real mean streak.” This idea that Ruby is not as innocent as she seems is continuously forced upon the

dots in the centre of the incident and reflected rays. Move the mirror to one side and use the ruler to join the dots to show the complete path of the ray. Add arrows so you know which direction the ray travelled. At the point where the ray reflects from the mirror add a line perpendicular to the mirrors surface - this is the normal line. Use the protractor measure the angle between the normal and the incident ray‚ and the normal and the reflected ray. Note these angles in a table and then repeat

Standardization/Conclusion Ray Kroc is often called the “Henry Ford of food services”. He realized that the mass production of fast food required the combination of precise measurements and an efficient assembly process. “There is a science to making and serving a hamburger”‚ Kroc once said.
