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

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

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

ANALYSIS The first recurrent image is the dark or darkness. Dark represents evil and hell. All of our fears rise in the dark. We can see that most of the mains scenes happen in a dark place or during the night. In fact‚ all the murders and treasons are done in darkness as if the dark could cover and hide the horrible deeds. For example‚ in act I scene V l. 53 to 56‚ Lady Macbeth says: “Come thick night‚ And pall thee in the dunnest smoke of hell‚ that my keen knife see not the wound it makes

any work of literary merit. By using symbolism‚ the work is given a deeper meaning. In Joseph Conrad’s Heart of Darkness‚ symbols are used to support the overall theme that imperialism only breeds evil. In the novel‚ one of the major symbols Conrad uses is the river which symbolizes man’s innate cruelty and also the unknown‚ both revealing that inside every man lies a heart of darkness that can be brought out under the right conditions. The setting for the majority of the novel is a river that stretches

specific objects around the room with out moving their body or heads and then leading into the discussion. This section I believe confused a lot of students because it started to lead to the misconceptions that a lot of students have about this topic of light‚ that we did not intend to happen. My Second student I chose for observation gave evidence as to why I think this is true. The student said‚ “My eyes couldn’t see behind me‚ because In the past I have seen the objects behind me‚ I couldn’t see them

Conclusion: Explain‚ in your own words‚ why different elements produce different colors of light when heated. Each element has a unique electron configuration. When heated‚ the electrons are energized and this leads to a higher quantum state. The color depends on the distance you have and the original electron configuration. Why do you think elements must be heated before they emit colored light?The light color is the electronic transitions between orbitals. When an electron drops to a

Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section.

The Giant Water Bug This story is about one phenomenon of nature‚ which the author observes ones when she was walking alone the edge. The frog was drained by a giant water bug. From the stylistic point of view the text falls into two parts. In the first part of the story the author uses a lot of literary stylistic devices such as epithets‚ trite metaphors and similes. For example metaphors: Frogs were flying all around me; similes: like a schematic
