Answer:

$60$

Answer C is correct

Explanation:

Silver has 47 electrons and 47 protons.

So,

$mass \: \: number = protons + neutrons \\ \: \: \: \: \: \: \: \: \: \: \: \: \: 107 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: \: \: \: \: \: \: \: 47 \: \: \: \: \: \: \: \: \: + \: \: \: \: \: \: \: \: \: \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: \: \: \: \: \: \: 107 - 47 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \: \: \: \: 60$

Sedaia [141]

Answer:

7.11 x $10^{14}$ Hz

Explanation:

The equation for converting wavelength to frequency is ν=c/λ, or the speed of light over wavelength. The speed of light is 3.00 x $10^{8}$ , and our wavelength here is 422 x $10^{-9}$ . All we have to do now is substitute our given values:

$\frac{3.00x10^{8} }{422x10^{-9}}$

After reduction, our answer comes out to be about 7.11 x $10^{14}$ Hz.
