Which of the following describes how the behavior of X-rays and gamma rays make these useful for treatment in the body?
They are blocked by the disease.
They are reflected by the normal cells.
They are absorbed by the skin.
They are transmitted through the body.
Is there light you cannot see?
Ultraviolet is another light we cannot see. In class we used a UV detector to measure the amount of UV light coming in through a window.
Young generations are able to see radio waves and X-rays but the older generations are not able to detect that type of light.
Yes, we can see all of the colors plus infrared and ultraviolet light. The rest of the types of light we are not able to see.
Red light is a light we cannot see. We read about how remote controls work.
Is there light you cannot see?
Older generations are able to see microwaves but the younger generations are not able to detect that type of light.
Infrared is a type of light that we cannot see. We observed that just like visible light, infrared light travels in straight lines and can be reflected, transmitted, and absorbed.
Violet light is type of light we cannot see. We learned in class that sunscreen blocks violet light.
Yes, we can see all light including x-ray and radio waves.
Both infrared light (IR) and ultraviolet light (UV) have wavelengths outside the range of wavelengths visible to humans. Infrared light has a wavelength that is too long to be seen, and UV light has a wavelength that is too short. UV light can be damaging to the skin, so the sunscreen makers want sunscreen to absorb all of the UV so that none of it reaches the skin. Why is it not a good idea to have sunscreen absorb visible light? What would the sunscreen look like if it absorbed all of the visible light that hit it? Select the best answer.
If sunscreen absorbed visible light, it would look black because it would scatter no light back to our eyes.
If sunscreen absorbed visible light, it would look bright white because it would scatter no light back to our eyes.
If sunscreen absorbed visible light, people would not be able to obtain a deeper tan.
If sunscreen absorbed all of the visible light, we would not be able to see the objects near us.
How does sunscreen work similar to color filters?
Sunscreens scatter the sunlight back out into the air and won’t let it touch your skin.
Just as a filter will only reflect a certain wavelength of color, sunscreen will only reflect the UV light but not the visible light.
Just as a filter will absorb some wavelengths of color but not others, sunscreen will absorb UV light but not visible light.
Just as a filter will absorb some wavelengths of color but not others, sunscreen will absorb all of the visible light but not UV light.
The prefix “infra” is defined as “below” Why does the prefix infra make sense in the term “infrared” ?
infrared does not produce much heat
infrared is below the temperature that can be recorded.
Infrared light has a wavelength just below the wavelength of red light
The prefix “ultra” can be defined as “beyond.” Why does the prefix ultra make sense in the term ultraviolet?
ultraviolet has a wavelength that is just beyond the wavelength of violet light.
ultraviolet light is beyond what sunblock is able to absorb.
ultraviolet light extends beyond measurable wavelengths

What do radio waves, microwaves, and x-rays have to do with what we have been studying?
They are all examples of visible light.
They are all examples of non visible light.
They are all examples of infrared light.
They are all examples of ultraviolet light.
