Question #d638b

Answer 1

The photon has a wavelength of `5.56xx10^12 m`

Explanation:

To answer this question, we can use the wave equation formula:

Where `lamda` is the wavelength and it has units of meters. `c` is the speed of light and it has a value of `3.0xx10^8 m/s`. `f` represents the frequency and it has units of Hertz or reciprocal seconds (`1/s`).

We know the frequency, `f`, and the speed of light since that is a constant. All we have to do is plug in the known values and solve for `lambda`:

`lambda = (3.0xx10^8 m/cancel"s")/((5.4xx10^-5)/cancel"s")`

`lambda = 5.56xx10^12 m`
