Answer
After performing the calculation, we find that the frequency of the light is approximately
.
Explanation
## Step1: First, we need to understand the relationship between the speed of light (c), the wavelength of light (λ), and its frequency (ν). The frequency of light is calculated by dividing the speed of light by its wavelength. ### The formula to calculate the frequency of light is:
## Step2: Next, we need to convert the given wavelength from nanometers (nm) to meters (m) because the speed of light is given in meters per second (m/s). ### To convert nanometers to meters, we use the conversion factor
. Thus,
.## Step3: Finally, we can substitute the values of the speed of light and the wavelength into the formula and calculate the frequency.### Substituting the values into the formula, we get
.
