[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.

The student filled four hollow metal cubes with cold water. Each cube was the same size but had a different surface colour. The cubes were then placed the same distance from an infrared heater. After 10 minutes, the student measu
