Which colour of light is diffracted most through diffractional grating?

Click For Summary
SUMMARY

The discussion centers on the diffraction of light through a diffraction grating, specifically analyzing the relationship between wavelength (λ) and the angle of diffraction (θ). The formula dsinθ=nλ establishes that as the wavelength increases, the angle of diffraction also increases, leading to the conclusion that lower frequency light is diffracted more. This confirms that for a given order of diffraction (n), light with a longer wavelength experiences greater diffraction.

PREREQUISITES
  • Understanding of the diffraction grating equation dsinθ=nλ
  • Knowledge of light properties, specifically wavelength and frequency
  • Familiarity with the concept of diffraction and its applications

the condition for a maximum is ;

dsinθ=nλ

let d and n be constant then θ (angle) increases as λ(wavelength) increases. So the θ will be the greatest for the highest value of λ ...that implies the frequency is lowest.
So I think light of lower frequency are diffracted much ...Am I right?

For a given order of diffraction (n), that is true.
