A point light source SSS is placed in front of a horizontal plane mirror. (i) Describe the position of the virtual image S′S'S′ relative to the object SSS and the mirror. (ii) Explain how a ray of light from the object reaches the observer's eye, and from where it appears to originate.
A student writes the following words in uppercase block letters on a sheet of paper: CHOICE\text{CHOICE}CHOICE, HIKE\text{HIKE}HIKE, CODE\text{CODE}CODE, and SHOE\text{SHOE}SHOE. She then places a mirror vertically on the paper along a horizontal line directly below the words (reflecting them across a horizontal axis). Which of the four words in the reflection looks different from the word written on the paper?
216 exam-style questions on CIE IGCSE Physics 3.2 Light, covering 3.2.1a Reflection of light, 3.2.1b Images in a plane mirror, 3.2.2 Refraction of light, 3.2.2a Refraction of light, 3.2.2b Total internal reflection, 3.2.2c Refractive index and critical angle, 3.2.2d Optical fibres, 3.2.3a Converging and diverging lenses, 3.2.3b Ray diagrams and the nature of images, 3.2.3c Virtual images and the magnifying glass, 3.2.3d Correcting long-sightedness and short-sightedness, and 3.2.4 Dispersion of light. Each one has a worked solution and a mark scheme showing where the marks go.
