Final answer:

The statement about the order of traffic lights is false as it does not properly represent the standard sequence. The correct order of light waves by increasing wavelength is blue, yellow, red and by increasing frequency is red, yellow, blue. In a free-body diagram for a traffic light, the horizontal tension forces should cancel each other out, and the sum of vertical tension forces should equal the weight of the light.

Step-by-step explanation:

Understanding Traffic Lights and Light Waves

The order of lights on a standard traffic light is red at the top, yellow in the middle, and green at the bottom. The statement in question would be false since the standard sequence from top to bottom on a traffic light does not include blue and the correct order is not provided.

For Part A, the order of light waves according to wavelength, from shortest to longest, is blue, green, yellow, and red. Consequently, the correct order would be blue, yellow, and then red.

For Part B, the order according to frequency, from lowest to highest, is the reverse of the wavelength: red, yellow, and blue.

When analyzing the forces acting on a suspended traffic light, the free-body diagram is crucial to determine the tension in the wires and ensure that the horizontal components cancel out, while the vertical components balance the weight of the traffic light.
