Question

Body scanners hard at security checkpoints at airports utilized frequency around 1.5x10^11 to attempt to detect objects by clothing. Calculate the energy of the electromagnetic radiation used by these devices

Expert Solution

Step 1

The energy of the electromagnetic radiation in the terms of the frequency is given by the expression as shown below:

$E = h ν$

Plugging the values in the above equation,

$ν = 1.5 \times 10^{11} s^{- 1} E = 6.626 \times 10^{- 34} \times 1.5 \times 10^{11} J E = 9.939 \times 10^{- 23} J$
