what is the frequency of an x - ray wave with an energy of 2.0×10^(-17) j?\nh = 6.626×10^(-34) j·s\n?×10^? hz

Answer:

$3.02\times 10^{16}$

Explanation:

Step1: Recall the energy - frequency formula

$E = h\nu$, where $E$ is energy, $h$ is Planck's constant, and $\nu$ is frequency.

Step2: Rearrange the formula for frequency

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

Step3: Substitute the given values

$E = 2.0\times 10^{-17}\text{ J}$, $h = 6.626\times 10^{-34}\text{ J}\cdot\text{s}$ $\nu=\frac{2.0\times 10^{-17}\text{ J}}{6.626\times 10^{-34}\text{ J}\cdot\text{s}}$

Step4: Calculate the frequency

$\nu=\frac{2.0}{6.626}\times10^{-17 + 34}\text{ Hz}\approx0.302\times 10^{17}\text{ Hz}=3.02\times 10^{16}\text{ Hz}$
