The driver applies the force shown in Figure 8. The force produces a moment about the pivot. How could the driver increase the moment about the pivot without increasing the size of the force? Infrared waves are transverse waves. 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 use...
