Answer 1

Question:

Calculate the wavelength of 5.09 x 10¹⁴ Hz frequency containing yellow light

__________________________________________________________

Answer:

as you know, c = λν

c = speed of light

ν = frequency

λ = wavelength

And, ν is given as 5.09 x 10¹⁴ Hz

So, λ = c/ν

c = 3 x 10⁸ m/s

λ = 3 x 10⁸ m/s/5.09 x 10¹⁴ Hz

λ = 0.589 x 10 ⁻⁶ m

λ = 589 x 10⁻⁹ m = 589 nm
