Question

what is the frequency of a radio wave with an energy of 8.3 x 10^(-24) j? h = 6.626 x 10^(-34) j·s ? x 10^? hz

Explanation:

Step1: Recall the energy - frequency formula

The formula is $E = hf$, where $E$ is energy, $h$ is Planck's constant, and $f$ is frequency. We need to solve for $f$.

Step2: Rearrange the formula for frequency

$f=\frac{E}{h}$

Step3: Substitute the given values

Given $E = 8.3\times10^{-24}\text{ J}$ and $h = 6.626\times10^{-34}\text{ J}\cdot\text{s}$, then $f=\frac{8.3\times 10^{-24}\text{ J}}{6.626\times 10^{-34}\text{ J}\cdot\text{s}}$

Step4: Calculate the value of frequency

$f=\frac{8.3}{6.626}\times10^{-24 + 34}\text{ Hz}\approx1.25\times10^{10}\text{ Hz}$

Answer:

$1.25\times 10^{10}$
