Light Effects Refraction‚ reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would

Std. 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 the 1950’s film Rear Window‚ director Alfred Hitchcock sets his entire work looking through a man‚ L.B. Jeffries’ rear window. Because of his broken leg‚ Jeffries is confined to his apartment‚ and even to his wheelchair. It is here‚ in his apartment‚ that the protagonist watches‚ or even spies on his neighbors. He draws conclusions on these people‚ but from a distance: across the apartment-building courtyard. In addition to this physical distance separating Jeffries from his neighbors‚ his perspective

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

Below there are three objects a mirror‚ a glass block and a prism‚ it shows and tells you underneath each of the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into

How does a Lens Refract Light? Different Lenses refract light in different ways. First‚ we will look at a double convex lens. Several light rays will approach the convex lens in a parallel manner. After they approach the lens‚ each ray will refract towards the normal. The light is passing from an optical less dense medium (Air) into a more dense medium (such as plastic or glass) at this boundary. Since the light rays are passing the boundary from a less dense medium in which light travels fast (optically

Introduction: Refraction‚ is the bending of a light ray when it pass from one medium to another. It occurred because the speed of the light travelled in different medium was inconsistent (Encyclopædia Britannica‚ 2016). Referring to the following diagram‚ i is the angle of incidence of light (assumed in a vacuum)‚ and the line that is perpendicular to the surface of the medium. r is the angle of refraction which indicate the angle between the line of normal and the light ray in the medium (Encyclopædia
