The illustration beneath displays the frequencies of different forms of electromagnetic radiation. Which of the following statements accurately contrasts the frequency and energy levels of infrared waves with ultraviolet waves? (1 point)
Infrared waves have frequencies that are lower than those of ultraviolet waves. As frequency and energy are inversely proportional, it implies that infrared waves also possess higher energy levels than ultraviolet waves.
Infrared waves exhibit frequencies lower than those of ultraviolet waves. As frequency and energy maintain a direct proportionality, it follows that infrared waves also possess lower energy levels compared to ultraviolet waves.
Infrared waves exhibit higher frequencies than ultraviolet waves. Given the direct proportionality between frequency and energy, it follows that infrared waves also possess more energy than ultraviolet waves.
Infrared waves have frequencies higher than those of ultraviolet waves. As frequency and energy are inversely proportional, this implies that infrared waves also possess less energy than ultraviolet waves.
Infrared waves have frequencies that are lower than those of ultraviolet waves. As frequency and energy are directly proportional, it implies that infrared waves also possess lower energy levels compared to ultraviolet waves.

Certain devices utilize electromagnetic waves to determine the position and velocity of an object. In these devices, the waves are emitted, reflected off the object, and then returned to the device. By understanding the wave's speed and the time it takes for the wave to return, the distance traveled by the wave can be calculated. Which category of wave would be the most secure choice for such a device? (1 point)
Opting for radio waves is the safest decision as they pose the least harm to organisms.
Choosing ultraviolet waves is the safest option since they are the most visually detectable.
X-rays would be the most secure option as they have the capability to go through various materials.
Opting for gamma waves is the safest decision due to their higher speed of travel.
