# The Frequency of Yellow Light Calculation

## What is the frequency of yellow light with a wavelength of 580 nm?

1. 5.2 × 10^14 Hz

2. 1.9 × 10^-17 Hz

3. 5.2 × 10^16 Hz

4. 5.2 × 10^12 Hz

5. 1.9 × 10^-15 Hz?

## Answer:

The frequency of yellow light with a wavelength of 580 nm is 5.2 × 10^14 Hz.

Let's convert the wavelength into meters first:

λ = 580 nm = 580 × 10^-9 m

Then we know that the frequency f is related to the wavelength by the following relationship:

f = c / λ

where c = 3 × 10^8 m/s is the speed of light. Substituting the numbers, we get the frequency:

f = 3 × 10^8 m/s / (580 × 10^-9 m) = 5.2 × 10^14 Hz

So, this is approximately the frequency of yellow light.
