Infrared radiation from surface

• What is a leslie cube?

  .it detects infared radiation
• How many surfaces does a Leslie cube have ?


  .4 surfaces
• Name the 4 surfaces of a leslie cube in order ?


  .shiny metallic

  .white

  .shiny black

  .matt black
• State the steps of how the surfaces that emit infrared radiation are detected ?

  1)fill up the leslie cube with hot water

  2)point a infrared detector towards the surfaces of the leslie cube
• What’s important to consider with the relationship with the infrared detector and the Leslie cube?

  .the distance needs to be same for reproducibility
• State the equipment needed for the absorption of infrared radiation?

  .heater

  .2 metallic plate

  .Vaseline

  .timer

  .and a pin
• State the steps for the detection of absorption of infrared radiation?

  1)turn on the heater

  2)start the timer

  3)you will see the matt black plate pin will melt first because it absorbs more infrared radiation
