Answer 1

Step-by-step explanation:

λν = c

Wavelength, λ (lambda), times frequency, ν (nu), equals the speed of light.

c = 3.0 x 108 m/s

===

We are given a wavelength of 483 nanometers. 1 nanometer = 1x10^-9 meter. 483nm = 4.83x10^-7 meters

---

λν = c

ν = c/λ

ν = (3.0x10^8 m/s)/(4.83x10^-7 m)

ν = 6.21x10^14 Hz (1/s)
