Question

The wavelength of a light wave as it passes through a material is 697.57 nm with a speed of 252,172,057.85 m/s. What is the frequency of this wave?

Answer 1

ν ≈ 3.62·10¹⁴ Hz - Light wave frequency

Step-by-step explanation:

Given:

λ = 697.57 nm = 697.57·10⁻⁹ m - The wavelength

c = 252 172 057.85 m/s - Light wave speed

_________________

ν - ? - Light wave frequency

ν = c / λ

ν = 252 172 057.85 / 697.57·10⁻⁹ ≈ 3.62·10¹⁴ Hz
