Adental x‑ray typically affects 175 g of tissue and delivers about 3.75 μj of energy using x‑rays that have wavelengths of 0.0265 nm. what is the energy in electron volts of a single photon of these x‑rays?

The energy in electron volts of a single photon of these X‑rays is 46697.5 eV.

Explanation:

Given that,

Wavelength = 0.0265 nm

We need to calculate the energy

Using formula of energy

Where, h = plank constant

c = speed of light

= wavelength

Put the value into the formula

We know that,

The energy in eV

Hence, The energy in electron volts of a single photon of these X‑rays is 46697.5 eV.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
