The smallest detail visible with ground-based solar telescopes is about 1 arc second. how large a region (in km) does this represent on the sun? hint: use the small-angle formula: angular diameter (in arc seconds) 2.06 ✕ 105 = linear diameter distance . (note: the average distance to the sun can be found in celestial profile: the sun.)

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
