Answer:I’m sorry but I do not understand what you are trying to ask
Explanation: not sure what text says
The region of the spectrum that best corresponds to light with a wavelength equal to;
1) The diameter of a hydrogen atom is; X-ray
2) The width of your pinky finger; microwaves.
3) The size of a virus; X-ray and Ultraviolet rays.
<h3>Electromagnetic spectrum</h3>
- From online tables, the diameter of an hydrogen atom is approximately 1 × 10^(-10) m but according to electromagnetic spectrum, any wavelength between 10^(-8) m and 10^(-12) m is an x-ray.
- From online tables, width of your pinky finger is 1.06 × 10^(-2) m but according to the electromagnetic spectrum the range between 1 and 10^(-3) m corresponds to microwave.
- The size of a virus has the range from 2 × 10^(-9) m to 4 × 10^(-7) m. This Range falls into x-ray or ultraviolet rays.
The complete question is;
What region of the spectrum best corresponds to light with a wavelength equal to:
(1) the diameter of a hydrogen atom
(2) the width of your pinky finger
(3) the size of a virus
Choices:
(A) radio
(B) mircowave
(C) infrared
(D) visible light
(E) gamma ray
(F) x-ray
(G) ultraviolet
