Two point sources (pixels) of monochromatic radiation can be resolved as close as 0.3 cm apart when viewing them at a distance of 1500 m through a lens 7 cm in diameter. what is the wavelength of the radiation? a) 2.1 x 10^-7 m b) 6 .3 x 10^-7 m c) 1.148 x 10^-7 m d) 0.643 x 10^-7 m e) 1.35 x 10^-7 m

Wavelength,

Explanation:

It is given that,

Two point sources (pixels) of monochromatic radiation can be resolved as close as 0.3 cm apart, x = 0.3 cm = 0.003 m

Diameter of lens, d = 7 cm = 0.07 m

Distance from the view line, D = 1500 m

We need to find the wavelength of the radiation. The formula for resolving power of Rayleigh criterion is given by :

So, the wavelength of the radiation is . Hence, this is the required solution.
