Question
A dental X-ray machine produces X-rays with a wavelength of $1.54$ angstroms, where one angstrom $\left(\right.$ symbol $\AA$ ) is equal to $10^{-10}$ meters and is a unit commonly used in spectroscopy. Calculate the energy of $6.022 \times 10^{25}$ of these X-ray photons in joules.
Step 1
We can use the formula for the energy of a photon, which is given by: \[E = \frac{hc}{\lambda}\] where \(h\) is Planck's constant, \(c\) is the speed of light, and \(\lambda\) is the wavelength of the photon. Show more…
