Which region of the electromagnetic spectrum is used by doctors to view the skeletal structure of the human anatomy? a) x-rays b) gamma rays c) radio waves d) visible light

The order of increasing wavelength (and decreasing energy) of the given radiations is:

Gamma Rays > X-Rays > Visible Light > Radio waves

X-rays due to the short wavelength and higher energies have the ability to penetrate through soft tissues like the skin or get absorbed by hard tissues like the bones. Thus, when the human anatomy is exposed to X-rays, bones appear white whereas the skin/tissues appear gray.

Ans: A)  X-rays are used by doctors to view skeletal structures

your correct option would be A

Explanation:

Doctors use an x ray to look at your skelton to see if you have a broken or fractured bone

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
