The speed of light is about 3.00 × 10 meters per second. What is the frequency of green light that has a wavelength about 500 nanometers? (1 nm = 10 m)

Formula :
v = λf
We have,
v = 3 × 10⁸ m/s
λ = 500 nm or 500 × 10-⁹ m
f = ?
So,
3 × 10⁸ m/s = 500 × 10-⁹ × f
f = 3 × 10⁸/500 × 10-⁹
f = 6 × 10¹⁴ Hz
