| Summary: | Seting up plans for study aid instrument to determine heat transfer by conduction, convection, and wave length in radiation method on colour of lighbulb have done. Heat transfer in metal is effected by kind of metal, every metal has different heat transfer, in sequence of four metals have different heat transfer from the higest to lowest are Aluminium, Capper, Brass dan iron. Heat transfer in the water by convection. From the different of temperature between upper and below are obtained heat transfer, 0.065 joule/sekon with relative error is 32.292%. Wave length on lightbulb. Surface colour is effected by kind and surface colour of lightbulb. Surface colour of lighbulb will be looked like light colour which is reflected. Efery light colour which is reflected by lightbulb painted colour has different wave length, the value of wave length every light colour is equivalent reverse with temperature in Kelvin. Based on value of research wave length in blue, yellow and red include in colour spectrum interval suitable with wave length every colour. From the highest to the lowest of wave length on lightbulb colurs are red, yellow and blue in sequence with wavelength 623.058 nm, 578.330 nm and 457.664 nm. |
