Redshift Nasıl Hesaplanır?
learn.whatIsHeading
Redshift (z) measures wavelength increase due to cosmic expansion or relative motion. Higher z indicates greater distance or recession speed.
Formül
Calculate z = (λ_obs - λ_rest) / λ_rest
- z
- (λ_obs - λ_rest) / λ_rest — (λ_obs - λ_rest) / λ_rest
Adım Adım Kılavuz
- 1Input observed and rest wavelengths
- 2Calculate z = (λ_obs - λ_rest) / λ_rest
- 3Estimate distance using Hubble constant
Çözümlü Örnekler
Giriş
z = 0.1
Sonuç
Recession velocity ~10,000 km/s, distance ~400 Mpc
Using H₀ = 70 km/s/Mpc
Kaçınılması Gereken Yaygın Hatalar
- ✕Confusing Doppler redshift with cosmological redshift
- ✕Using non-relativistic formulas for high z
Sık sorulan sorular
Does redshift mean object moving away?
Usually yes, but expansion also redshifts distant objects even in static space.
