=Light & Matter=

**key knowledge **
 * describe transverse waves in terms of
 * amplitude
 * wavelength
 * period and frequency
 * calculate wavelength, frequency, period and speed of travel of light waves, v = fλ= λT 
 * investigate and analyse the behaviour of light using ray diagrams including
 * reflection, i = r
 * refraction, Snell’s Law
 * total internal reflection, critical angle;
 * (any form of image location is not required) 
 * explain polarisation of visible light and its relation to a transverse wave model; 
 * describe light using a wave model and a particle model; 
 * compare the wave model and the particle model of light in terms of whether they adequately describe reflection and refraction; 
 * identify visible light as a particular region of the spectrum of electromagnetic radiation and that all light travels at the speed of light in a vacuum, c; 
 * explain the colour components of white light as different frequencies of light combining to appear white; 
 * explain colour dispersion in prisms and lenses in terms of refraction of the components of white light as they pass from one medium to another.

Energy booklet solutions


Please read and summarise this chapter by making your own summary notes. Your summary must include the following


 * 'Position, distancem displacment, speed, velocity, acceleration
 * Origin
 * Difference between distance and displacement
 * Vectors and scalars
 * Instantaneous speed and velocity
 * Speed and velocity formulas
 * Converting m/s to km/hr
 * Formula for acceleration
 * Displacement-time graphs
 * Area under distance/displacement time graphs...
 * Equations of motion

By first week of term 3 you must show that you have created summary notes for the motion chapter and Newtons Laws (Ch 4 & 5)
