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

Answer:

$E=6.7\times 10^{-26}\ J$

Explanation:

Given that,

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

The energy of a photon is given by :

$E=h\nu$

Where

h is Planck's constant

$E=6.63\times 10^{-34}\times 101.5\times 10^6\\\\E=6.72\times 10^{-26}\ J$

or

$E=6.7\times 10^{-26}\ J$

So, the energy of the photon is $6.7\times 10^{-26}\ J$. Hence, this is the required solution.
