57:01 school buses are yellow because yellow color is the most sensitive color to our eyes hence the buses can be easily spotted and the other drivers could maintain a safer distance for the safety of children. thank you for your explanation sir it was really helpful.

Our eyes are most sensitive to yellow colors and are least sensitive to violet and red colors. Due to this reason school buses are painted yellow. As a result, the school buses can be easily identified by other drivers and a safe distance can be maintained to ensure the safety of children.

30:48 hypermetropia = (i) the focal length of the eye lens is too long, or (ii) the eyeball has become too small. Myopia = The eye lens becomes too convex or curved Depth of the eyeball is too much i.e. eyeball lengthened from front to back. When the length of the eyeball is too long as compared to the focusing power of the lens of the eye and cornea. Because of this, the light rays focus at a point in front of the retina and not on the retina itself. 57:05 Our eyes are most sensitive to yellow colors and are least sensitive to violet and red colors. Due to this reason school buses are painted yellow. As a result, the school buses can be easily identified by other drivers and a safe distance can be maintained to ensure the safety of children.
