Now think back to the fan. Suppose the fan(composed of 5 blades) is set to rotate at a fixed frequency of 600 RPM (revolutions per minute). This means that each blade completes revolutions per second. In order to freeze the fan, the strobe light must catch each blade in exactly the same location every time it flashes. This means that the frequency of the strobe light must be adjusted according to the frequency of the fan. Would the blades freeze if the frequency of the strobe light was set to 600 flashes per minute? yes / no (highlight one). Would the blades freeze if the frequency of the strobe light was set to 300 flashes per minute? yes/no (highlight one).
