Complete the sentence. [1 mark] In a transverse wave, the direction of oscillation is to the direction of energy transfer by the wave. A student investigated how the colour of a surface affects the rate at which the surface emits infrared radiation. Figure 1 shows some of the equipment used. Figure 1 . The student wrote the following hypothesis: ‘The black-coloured flask will emit more infrared radiation than the silver-coloured flask during 10 minutes of cooling.’ Describe a method to test this hypothesis.
