Radiation Absorption Disc Set

Aluminium discs each with different durable anodised finish-matt black, mirror black, matt silver and mirror silver. Bonded to the reverse of each disc is 30-650°C liquid crystal thermometer. These discs show in a clear and measurable way how absorption of heat radiation depends on surface colour and texture. The very low heat capacity gives quick results, meaning that many more experiments can be completed in each lesson. The discs can be used to investigate rates of cooling, the effects of filters and reflectors, inverse square law and equilibrium between absorption and emission. Supplied with a holder and storage box.
