one form of x - band radar has a frequency of 8.0 ghz, which is the same as 8.0×10^9 hz. what is the energy…

Explanation:

Step1: Recall energy - frequency formula

The energy of a photon is given by $E = hf$, where $E$ is energy, $h$ is Planck's constant, and $f$ is frequency.

Step2: Substitute values

We know that $h = 6.626\times10^{-34}\ J\cdot s$ and $f = 8.0\times 10^{9}\ Hz$. $E=(6.626\times 10^{-34}\ J\cdot s)\times(8.0\times 10^{9}\ Hz)$

Step3: Perform multiplication

Using the rule of exponents $a^m\times a^n=a^{m + n}$, we have $E=(6.626\times8.0)\times10^{-34 + 9}\ J$. $6.626\times8.0 = 53.008$, so $E = 53.008\times10^{-25}\ J$. In scientific - notation, $E=5.3008\times 10^{-24}\ J$.

Answer:

$5.3008\times 10^{-24}$
