Possession
> Snell's law experiment: Draw a labelled setup, describe the steps of experiment precisely, plot a suitable graph to find refractive index of the semi-circular block
> Apply Snell's law to solve problems (P.43)
> Refraction is the result of change in speed of light in different medium
> Refractive index =c/v
> Dispersion is the result of different colours travels at different speeds in a medium (such as glass)
> Explain daily application using ray diagram that shows refraction (P>48-51)
> Vocabulary: refracted (adj) ray, angle of refraction (noun)

Possession
> Measuring critical angle experiment: Draw a labelled setup, describe the steps of experiment precisely
> Total internal reflection occurs only when light travels from optically denser (slower) to less dense (faster) medium.
> Apply Snell's law to find critical angle (P.55)
> Application of total internal reflection (P.57)
> Vocabulary: prism, binoculars, periscope, optical fibres, cladding, mirage, fish-eye view
