During the presentation of lecture information on wave characteristics and properties, students take notes using a handout. Light is a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Salt and oil are both polar while water is not. Know all vocabulary. The activities listed below the ppt are used during the lesson and are identified in the ppt for use where they are most likely appropriate. The splitting up of sunlight or white light into its colours is called dispersion of light. Number of Views: 234. Light waves are like other kinds of waves. Light Class 8 Science Chapter 16 as per NCERT Book used in CBSE and other Schools. The splitting of white light into its seven colours constituent is known as : (a) refraction (b) dispersion (c) reflection (d) deviation. ii) When light falls on objects, it reflects the light and when the reflected light reaches our eyes then we see the objects.. The eye 9. Empty reply does not make any sense for the end user. The student will explain that thermal energy in a material consists of the ordered and disordered motions of its colliding particles. Chapter 5 - Energy & Power. Rutheford's atomic model could not explain the chemical properties of elements. (1) The kaleidoscope consists of three long and narrow strips of plane mirrors inclined at 60° to one another forming a hollow prism, and fitted into a cardboard tube. A photon is the smallest possible particle of electromagnetic radiation. When one field vibrates—so does the other. UV Rays.

An object becomes visible when light emitted or reflected by it reaches our eyes. Light Disperses (dispersion) Light separates into its constituent colors. One of the important tasks for fifth-grade readers is to learn how to dissect . The ray of light which falls on a mirror is known as a/an: (a) incident ray (b) emergent ray (c) reflected ray (d) transmitted ray. The pupil is the opening of the eye through which the light enters. 5.3. . Salt and water are both polar while oil is nonpolar. Light comes from different sources called light sources; our main natural light source is the sun. They have crests, troughs, wavelength, frequency and speed. EM wave is a disturbance that involves transfer of electric. Light waves are transmitted through transparent materials (may be clear or colored material such as filters) that allow most of the light that strikes .

Physics, Computer Science and Engineering - Redirecting - Christopher . - Light is absorbed (propagation is stopped) - Medium is opaque • If light wave frequency ≠ molecules resonant frequency - Light is reradiated and propagated forward through medium - Medium is transparent • In a solid or liquid, propagation is in straight line • In a gas, propagation is less organized and scatter increases LIGHT • Light is an electromagnetic wave, namely the wave the vibration of which is electric field and magnetic field. What is the speed of EM waves? Sound waves are transmitted through solids, liquids, and gases. Properties of Visible Light. Quarter 1 - Module 8 Illustrating the Slope of a Line. 2) Reflection of light :- When light falls on a polished or shiny surface it changes its direction. A photon is the smallest possible particle of electromagnetic radiation. Light is only a small part of them Electromagnetic Spectrum Speed of E/M Waves From last chapter, we found that V = f * l We also said that the speed of a wave in a certain medium is always constant. 6. Rays of Light Incident Ray - leaves the object and strikes the mirror Reflected Ray - leaves mirror and strikes your eye The reflected ray is on the line of sight from the image to your eye. Classify transparent, translucent and opaque materials 4. Number of Views: 1333. The best example of this is wearing the color black outside. 4. 5 Light is made of little particles called photons. Air Takes Up Space Air Has Weight Air Has Pressure 15 Pounds per Square Inch Air Expands When Heated Able to take in more moisture Air Contracts When Cooled Will release moisture (Dew Point) Air in a High Pressure Area will Rush into a Low Pressure Area.

Streak is the color of a rock after it is ground into a powder, and luster tells how shiny a . Reflection of light 1. Part 1. Rocks are made out of minerals and have many different properties, or characteristics. The light emitted by an electron moving from a higher to a lower energy level has a frequency directly proportional to the energy change of the electron. Lesson Summary. The sun is our main source of light on Earth. Prevents any light from passing through it. Properties of Sound, continued Speed of Sound in Various Mediums Speed of Sound Properties of Sound, continued Loudness is determined by intensity. rocks, air, light, and soil. . loudness: depends partly on the energy contained in the sound wave intensity: describes the rate at which a sound wave transmits energy through a given area of a medium Intensity depends on the . It is highly visual, with appropriate images and pictures supplementing the text on each slide. Here are the PowerPoint Presentations & a few Flash files available for most of the chapters: Chapter 1 - Motion. 4 Light travels in a straight line. Waves have the following behaviors: Transmission.
