In The Visible Region, The Dispersive Powers And The Mean Angular Deviations For Crown Glass And Flint Glass Prism Are Omega, Omega1 And D, D1 Respectively. The Condition For Getting Dispersion With Zero Deviation When The Two Prisms Are Combined Is

Given:

Dispersive power – ω, ω’

Mean deviation – d, d’

Dispersive power, \(\omega = \frac{angular dispersion}{mean deviation}\)

⇒ Angular dispersion = Dispersive power * mean deviation

⇒ ω d + ω’d’ = 0

Therefore, the condition for getting dispersion with zero deviation when the two prisms are combined is ω d + ω’d’ = 0.
