Answer 2

please matk me as brainiest

Explanation:

The relationship between speed of light (c) , wavelength (λ) (pronounced lambda), and frequency (ν) (pronounced noo), is given mathematically as c=λ⋅ν . To find the frequency of a photon with a wavelength of 2.5×10−9m , rearrange the equation to isolate ν and solve. The unit for frequency is 1/s , or Herz (Hz).
