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) Responses
X-rays would be the most secure option as they have the capability to go through various materials.
Choosing ultraviolet waves is the safest option since they are the most visually detectable.
Opting for radio waves is the safest decision as they pose the least harm to organisms.
Opting for gamma waves is the safest decision due to their higher speed of travel.
Opting for gamma waves is the safest decision due to their higher speed of travel.
is this correct
No, the correct answer is opting for radio waves is the safest decision as they pose the least harm to organisms.
is this actually true
Yes, it is true that radio waves pose the least harm to organisms compared to other types of waves such as X-rays or gamma waves. Radio waves have lower energy and longer wavelengths, making them less harmful to living organisms.
Colleen replicates an X-ray machine by covering an open shoebox with a screen and positioning a square cardboard piece in the center. She uses sand to simulate X-ray radiation, sprinkling it over the screen. Upon removing the screen, she observes an outline of the square cardboard. What does the cardboard symbolize in her simulation?(1 point) Responses
the areas that remain black on the X-ray
the bones that look white in an X-ray
the person being scanned with X-rays
the veins that look white in an X-ray
