Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

emergency vehicles. Red color is being chosen as the color for the emergency vehicles strobe lights is because of the night vision capability by using this color. It cannot be denied that red color is more easily to be notice if compared to other color. Red color can catch more attention and alert when we saw red because red is signal us about danger. Advantages and Disadvantages White: light is the most effective attention-getting signal‚ containing all visible spectral wavelengths

Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must

VIII - Subject: Physics Feb Class Worksheet– Topic: Reflection of Light Name:__________________Div.____ Roll No. ____ Date: ________ Reflection of Light – The return of light into the same medium after striking a surface is called reflection. Some terms related with reflection are – 1. Incident Ray - The light ray striking a reflecting surface is called the incident ray. 2. Reflected Ray – The light ray obtained after reflection from the surface in the same medium in

Renaissance architecture evolved in the beginning of the 15th century‚ succeeding Gothic Architecture and lasted till the early 17th century. Renaissance architecture can also be defined as a restoration of Greek and Roman Architecture and its principles. As aforementioned‚ Greek and Roman architectural as well as artistic knowledge was lost due to the dark ages‚ and Renaissance sought to bring back that lost precious knowledge. Naturally Renaissance architecture saw use of architectural elements

Name:_______________________ Class: F.___ Class No:_____ 1. Light and sight We see an object when light from that object enters our eyes. Many rays from the object enter the eye at the same time. However‚ in diagrams‚ we only show two or some rays only. A point gives out many rays but we usually draw _two___ rays to mark out the cone of rays from the point of the object reaching the eye (Fig 1a). To indicate that the eye sees the whole object‚ two cones of rays are drawn from the two

Purpose: To 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:
