A canvas tent has a single,tiny hole in its side.While inside the tent,you observe on the wall of the tent which is 2.0 m away from your eye a dot (due to the Sun's light incident upon the hole) of width 2.0 mm,with a faint ring around it.What is the size of the hole in the tent?
A) 0.76 mm
B) 1.24 mm
C) 0.31 mm
D) 0.62 mm

The size of the hole in the tent is 0.76 mm. This can be determined by using the formula for the diameter of the diffraction pattern:d = 2.44 * lambda * D / wwhere:d is the diameter of the diffraction patternlambda is the wavelength of lightD is the distance between the hole and the screenw is the width of the holeIn this case, lambda = 550 nm, D = 2.0 m, and w = 2.0 mm. Plugging these values into the formula, we get:d = 2.44 * 550 nm * 2.0 m / 2.0 mm = 0.76 mm
