Answer :
Answer:
λ2 < λ1
Explanation:
- Young's experiment of interference of light when passed through a slit has determined a result. We will use an expression derived from the results that relates wavelength and and the spread of the interference pattern using:
sin (Q) = n*lambda / d
Where,
n is the order of fringe about the central order
lambda is the wavelength of light
d is the space between grating
Q is the angle between the two successive interference fringe
- So in our case using a light of wavelength lambda 2 the pattern got closer together or we could say that angle Q got smaller. According to the relationship given we can see as angle Q decreases when lambda decreases. So we can conclude that λ2 < λ1.
