Chapter 5: Ray model of light
types of mirrors
plane mirror
upright, same size as object, virtual, laterally inverted
convex mirror
virtual, upright and magnified (commonly used when a magnified image is needed e.g. car headlights)
concave mirror
virtual, upright and diminished (commonly used when a large area needs to be seen
luminous: give out light on its own
2 laws of reflection
the angle of incidence is equal to the angle of reflection
the incident ray, the reflected ray and the point of incidence all lie on the same plane
point of incidence
incident ray
reflected ray
normal
angle of incidence
angle of reflection
real image
light falls where the image is so it can be caught on screen
virtual image
image can be seen but no light rays are passing through the location of the image, so the image cannot be caught on screen
non luminous: cant produce light, reflects light
refraction
bending of light as it passes from one transparent material to another due to the difference in the speed of light in the two different media
