year 9 reflection

• Specular reflection causes parallel light rays to all be reflected in the same direction.
• • Smooth, shiny surfaces produce specular reflections, and rough surfaces produce diffuse reflections.
• transverse wave- A wave in which the particles move up and down at right angles to the direction it travels in
• diffuse reflection- The type of reflection caused by rough surfaces, which causes light rays to be reflected in all direction
• The angle at which the light is reflected depends on the angle it hits the mirror, and a ray diagram can be used to show the path of the light rays.
• The angle the ray is reflected is always the same as the angle the light hits the mirror, with both angles being measured from the normal.
• Modern computer games use ray tracing, applying the law of reflection to rays of light to create realistic reflections – improving the quality of the computer game graphics.
