Answer:

6.21 x 10¹⁴ Hz

Step-by-step explanation:

The frequency can be found using the following equation:

λ = c / f

In this equation,

-----> λ = wavelength (m)

-----> c = speed of light (3.0 x 10⁸ m/s)

-----> f = frequency (Hz)

After converting the wavelength from nm to m, you can plug the given values into the equation and simplify to find the frequency.

483 nm 1 m
--------------- x --------------------- = 4.83 x 10⁻⁷ m
1 x 10⁹ nm

λ = c / f <----- Given equation

4.83 x 10⁻⁷ m = 3.0 x 10⁸ m/s / f <----- Insert values

(4.83 x 10⁻⁷ m) x f = 3.0 x 10⁸ m/s <----- Multiply both sides by f

f = 6.21 x 10¹⁴ Hz <----- Divide both sides by 4.83 x 10⁻⁷
