The Doppler shift, describing the way in which the wavelength λ₀ of light emitted by a moving object is detected as a different wavelength λ by a stationary observer (with v the object velocity and c the velocity of light), is given by: A)(λ -λ ₀)/λ ₀ = v/c. B)λ.λ₀ = vc. C)λ - λ₀ = (v - c). D)λ /λ ₀ = v/c.

The Doppler shift equation is given by (λ -λ0)/λ0 = v/c, where λ is the observed wavelength and λ0 is the original emitted wavelength. This equation can also be written as (λ - λ0) = λ0(v/c). Rearranging, we get (λ - λ0)/λ0 = v/c, which is equivalent to option A.
