The distance from the screen with an aperture to the observation point of 1 m. The screen is illuminated by monochromatic light with a wavelength of 5 x 10 -7 m. Calculate the radius of the fifth Fresnel zone if: a point light source and the distance between it and the screen 0.5 m; wavefront incident on the screen is flat, light incidence is normal.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
