Web27 Oct 2024 · Oct 27, 2024. FWHM or Full Width at Half Maximum is the width of the output spectrum of a light source measured at half of its maximum amplitude. It is measured between the point on the output spectrum curve where power has decayed to half of its peak value. FWHM is a quantitative method used to specify the spectral width of a light source. Web19 Aug 2024 · (1) (1) X ∼ N ( μ, σ 2). Then, the full width at half maximum (FWHM) of X X is FWHM(X) = 2√2ln2σ. (2) (2) F W H M ( X) = 2 2 ln 2 σ. Proof: The probability density function of the normal distribution is f X(x) = 1 √2πσ ⋅exp[−1 2( x− μ σ)2] (3) (3) f X ( x) = 1 2 π σ ⋅ exp [ − 1 2 ( x − μ σ) 2] and the mode of the normal distribution is
