Laser through a gredient of sugar

Demo :

  • Bismuth
  • Laser
  • Water tank
  • sugar gradient (laying sugar cubes on botten night before)

Risk assessment:

  • Be mindful where laser is shining.



Target:

Reflection

• Describe the features of a mirror image

• Identify examples of specular reflection and diffuse scattering

• Use appropriate equipment safely with guidance


• Explain how images are formed in a plane mirror

• Explain the difference between specular reflection and diffuse scattering

• Use appropriate equipment and take readings safely without help


• Draw a ray diagram showing how an image is formed in a plane mirror

• Extend the concept of specular reflection and diffuse scattering by applying this to models and other examples

• Take accurate readings using appropriate equipment and working safely

Refraction

• Describe what happens when light is refracted

• Describe features of the image formed by a lens

• Record some observations as a diagram with help


• Describe and explain what happens when light is refracted

• Describe what happens when light travels through a lens

• Record observations using a labelled diagram


• Predict the path of light using a model of light refraction

• Explain what happens when light travels through a lens

• Record observations using labelled diagrams, and apply this to other situations
