You're asking about the frequency of light with a wavelength of 4.86 x 10^-7 meters. Here's how to calculate it:

Understanding the Relationship

* Wavelength (λ): The distance between two consecutive crests (or troughs) of a wave.

* Frequency (f): The number of waves that pass a point in one second.

* Speed of Light (c): The speed at which light travels in a vacuum, approximately 3 x 10^8 meters per second.

These three quantities are related by the following equation:

c = fλ

Solving for Frequency (f)

1. Rearrange the equation: f = c / λ

2. Plug in the values:

* c = 3 x 10^8 m/s

* λ = 4.86 x 10^-7 m

3. Calculate:

f = (3 x 10^8 m/s) / (4.86 x 10^-7 m)

f ≈ 6.18 x 10^14 Hz

Therefore, the frequency of light with a wavelength of 4.86 x 10^-7 meters is approximately 6.18 x 10^14 Hz.
