283224 Newton's rings are observed normally in reflected light of wavelength \(5000 \AA\). The diameter of the \(10^{\text {th }}\) dark ring is \(0.005 \mathrm{~m}\). The radius of curvature of the lens is

283225 A screen is placed \(2 \mathrm{~m}\) away from a narrow slit. It the first minimum lies \(5 \mathrm{~mm}\) from either side of the central maxima, when plane waves of wavelength \(5 \times 10^{-7} \mathrm{~m}\) are used, the slit width is

283226 Assertion: A white source of light during interference forms only white and black fringes.
Reason: Width of fringe is inversely proportional to the wavelength of the light used.

283227 Assertion: A famous painting was painted by not using brush strokes in the usual manner, but rather a myriad of small colour dots. In this painting the colour you see at any given place on the painting changes as you move away.
Reason: The angular separation of adjacent dots changes with the distance from he painting.

283232 In a Young's experiment, two coherent sources are placed \(0.90 \mathrm{~mm}\) apart and the fringes are observed one metre away. If it produces the second dark fringe at a distance of \(1 \mathrm{~mm}\) from the central fringe, the wavelength of monochromatic light used would be-
