The reason for a swimming pool to appear less deep than the actual depth is (a)refraction (b)light scattering (c)reflection (d) interference
option A..The obvious intensity will appearance much less that its actual intensity because of the refraction of mild. Refraction is the bending of a wave while it enters a medium wherein it’s pace is different. The refraction of mild whilst it passes from a quick medium to a sluggish medium bends the mild ray towards the regular to the boundary among the 2 media. The quantity of bending relies upon at the indices of refraction of the 2 media and is defined quantitatively through Snell’s Law.
