The cohrence length of a light source is 2.45×10raise to power-2 calculate width of spectral line
To calculate the width of a spectral line, we need to use the formula for the coherence length:
Coherence Length (L) = λ^2 / Δλ,
where
- L is the coherence length
- λ is the wavelength of the light source
- Δλ is the width of the spectral line
Given that the coherence length (L) is 2.45x10^(-2) and assuming we have the wavelength (λ), we can rearrange the formula to calculate the width of the spectral line (Δλ).
Δλ = λ^2 / L
Now, let's assume that the wavelength (λ) is known. Please provide the value of the wavelength so that I can calculate the width of the spectral line for you.
