1.describing wave
1.1
-Describe wave motion using vibration in rope and spring, on wave in a ripple tank
-understand that wave transfer energy with out transferring matter.
-Compare transverse and longituding waves and give suitable example of each.
1.2 Properties of wave motion
-Define the speed, frequency wavelength, period and amplitude of wave.
-State that is meant by tern wave front
-recall and apply the relationship to solve related problems.
1.3 Wave production and the ripple tank.
-describe the effect of refraction reflection and clepend change on wave in a ripple tank.
2. Light
2.1 What is light?
-understand how light travels and how we able to see
2.2 Reflection of wave
- Understand the term used for reflection normal, angle of incidence and angle of reflection.
2.3 Construction Ray diagrams
- apply the principles of reflection in construction measurements and calculate.
2.4 Reflection at plane surface
-understand the tern used for refraction normal, angle of incidence and angle of refraction
-recall the relationship to solve related problems.
- Define refraction index of a medium is term of ratio of the speed of light in vacuum to that in the medium.
2.5 total internal reflection
-explain critical angle and total internal reflection
-indentity the main idea in total internal reflection and State the advantage of its use in apical fibers.
2.6 thin converging lens.
-descried the action of a thin lens both converging and diverging on a term of light.
2.7 Ray diagrams for lens.
- Draw ray diagram to illustrate for motion of real and virtual image of on object be a thin converging lens.
3. Sound
3.1 what is sounds
-describe how sound is produced by vibrating source
- describe how travel as longitudinal wave using the process compression and rare fraction.
3.2 Transmission of sound
- explain that sound need a medium for transmission and that speed of sound if sound differ in solid, liquids and gasea.
3.3 Reflection of sound
-describe how the reflection sound wave produce an echo and how this may be used to measure distance
3.4 ultrasound
-define ultrasound and describe one use of ultrasound i.g. quality control and pregnantal scanning.
3.5 Pitch and loundness
-relate of a sound wave to its amplitude and pitch to its frequency.
