Light with a wavelength of 450 nm shines through a lens with an aperture diameter of 0.85 cm. Use Rayleigh's criterion to determine the limiting angle of resolution. (1 nm = 10^-⁹m)

Question

Quizplus · Accepted Answer

Rayleigh's criterion states that the limiting angle of resolution is given by:$$	heta = 1.22 \frac{\lambda}{D}$$where:$$	heta$$ is the limiting angle of resolution$$\lambda$$ is the wavelength of light$$D$$ is the diameter of the aperturePlugging in the given values, we get:$$	heta = 1.22 \frac{450 	imes 10^{-9} 	ext{ m}}{0.85 	imes 10^{-2} 	ext{ m}} = 6.5 	imes 10^{-5} 	ext{ rad}$$Therefore, the correct choice is A.
