DHANYA JOE(1414918). • Explain True Life Scenario. 3. REFLECTION AND REFRACTION Starter Answer 10 everyday uses of mirrors or reflections  As an example, a beam of light striking water vertically will not be refracted, but if the beam enters the water at a slight angle it will be refracted to a very small degree. These are more effective in scattering light of shorter wavelengths at the blue end than the light of longer wavelength at the red end. Uses  Optical communications uses sequences of light pulses to transmit information through an optical fibre network. This exaggerates the refraction of the light, and as it leaves the prism, it is dispersed into a continuous spectrum. However, dispersion also has an effect in many other circumstances: for example, group velocity dispersion (GVD) causes pulses to  Dispersion of light occurs when white light is separated into its different constituent colors because of refraction and Snell's law. The research Regarding students' ideas would suggest that their misconceptions related their experience, particularly wording and terms using in everyday life. This is called 'dispersion', and allows us to work out what stars are made of by looking at the mixture of wavelengths in the light. 1 The physical phenomenon.
