Question

Calculate the energy of a photon from an FM radio station at a frequency of 101.5 MHz. Express the answer in scientific notation. Use the caret symbol (^) before the exponent. Use an x for the times sign. Include correct unit(s). Pay attention to sig figs. Space things normally and consistently. *

Answer 1

`E=6.7* 10^(-26)\ J`

Step-by-step explanation:

Given that,

The frequency of an FM radio station is 101.5 MHz i.e.
`101.5* 10^6\ Hz`

The energy of a photon is given by :

`E=h\\u`

Where

h is Planck's constant

`E=6.63* 10^(-34)* 101.5* 10^6\\\\E=6.72* 10^(-26)\ J`

or

`E=6.7* 10^(-26)\ J`

So, the energy of the photon is
`6.7* 10^(-26)\ J`. Hence, this is the required solution.
