A student learned that radio waves are deemed safe, whereas x-rays are considered hazardous. The student examine the provided electromagnetic spectrum. Given this information, which statement can the student most efficiently articulate to clarify the distinction between radio waves and x-rays.
The heavier particles of x-rays, indicated by their shorter wavelength, enable them to penetrate matter more extensively
The greater energy of x-rays is reflected in their shorter wavelength
The higher temperature and increased likelihood of causing burns are associated with the shorter wavelength of x-rays
The x-rays with their shorter wavelength cause them to be less common
The greater energy of x-rays is reflected in their shorter wavelength.
X-rays find application in medical scenarios for generating images of bones, tissues, and organs. While X-rays can penetrate tissues like skin, their ability to penetrate bone is comparatively lower. This property of X-rays is attributed to which characteristic of the rays?
Their long wavelengths
their large amplitudes
their short wavelengths
their small amplitudes
Their short wavelengths.
A student is tasked with suggesting a design for a device capable of generating an image resembling the one depicted below, revealing the interior of the human body. Which statement most effectively justifies why the student should advocate for the utilization of X-rays in the device.
The luminosity of X-rays results in an extended duration once they are generated by a machine.
The scarcity of X-rays in nature allows them to be employed in machines without interference from other X-rays, preventing image blurring .
The high velocity of x-rays permits their safe usage on human patients.
The elevated energy levels of x-rays enables them to penetrate through the human body
The elevated energy levels of x-rays enables them to penetrate through the human body.
the image depicts a window made of stained glass. How does a stain glass window alter the white light that passes through it?
Reflecting different wavelengths of light
Refracting different wavelengths of light
Absorbing different wavelengths of light
Diffracting different wavelengths of light
Reflecting different wavelengths of light.
A scientist crafted the model to illustrate the behavior of a light ray. For what reason might a scientist create this model depicting the behavior of a light ray?
To explain that light travels in a straight line until it transitions from one material to another
To explain that light travels in a straight line even when transitioning from one material to another
To clarify that light follows a curved trajectory until it transitions from one material to another
To clarify that light follows a curved trajectory even when transitioning from one material to another
To explain that light travels in a straight line until it transitions from one material to another.
The image beneath displays a duck floating in a pond. Why does it seem like there is an additional duck head in the water?
The duck disperses the light, creating numerous small refractions that converge into an image
The ponds water refracts sunlight, creating a mirrored image
The ponds bottom absorbs the light and subsequently projects it towards the surface in the form of an image
The molecules in the atmosphere bend the light, causing it to separate into two images
