have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite and to verify Snell’s Law. Materials: Lucite block‚ light ray box‚ paper‚ pencil‚ ruler and protractor. Procedure: First‚ place the

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

One of the NFL’s greats and future Hall of Famer Ray Lewis is an inspiration to people all over the world. The struggles and hardship he endured light a fire in him to strive for better even when the cards weren’t in his favor. His dedication made him into a strong and wise leader of a Super Bowl winning team. As a motivational speaker as well he helps people get confidence to make something of themselves no matter what. His story lets people know that even though times get rough if you fight and

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

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. Along those lines‚ Kroc required exact specifications on all of his beef patties: Fat content: below 19% Weight: 1.6 oz Diameter: 3.875 inches Onions: ¼ oz Kroc even had a laboratory in suburban

The design was made such that after harvesting and drying the palay‚ the dryer can also serve as storage of dried palay. Rice hulls served as fuel for the dryer. It can dry to a maximum of 20 sacks per drying period. The performance and efficiency of the dryer were tested as the drying rate‚ final weight of the grain‚ moisture reduction per hour‚ fuel consumption rate‚

Hypothesis: If the light goes through different mediums‚ then the light will bend because it is slowing down as it passes through the medium. Equipment: Semicircular plastic dish Polar graph paper Ray box with single slit Water Syrup Experimental Design: A ray box with a single slit will be shone through a semicircular dish through air‚ water‚ and syrup‚ on top of polar graph paper to see how the light will bend. Procedure: A semicircular dish was placed at the centre

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
