The photon energies used in different types of medical x-ray imaging vary widely, depending upon the application. single dental x rays use photons with energies of about 25 kev. the energies used for x-ray microtomography, a process that allows repeated imaging in single planes at varying depths within the sample, is 2.5 times greater.

what are the wavelengths of the x rays used for these two purposes?

1. Single dental x-rays:

The energy of the photon is

Using the conversion factor

we can convert it into Joules:

The relationship between photon energy and wavelength is

where

is the Planck constant

is the speed of light

E is the energy

Substituting into the formula, we find

2. Microtomography:

The energy of these photons is 2.5 times greater, so

And by applying the same formula used at point 1, we find the corresponding wavelength:

its c its is a mixture of gases

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
