电和光的区别？
电和光的区别？
其实没区别。光是原子里的外层电子受到激发而产生的电磁波.光与电是两种截然不同的现象，没有直接联系.光可以生电，如太阳能电池；电可以生光，如所有电光元件。
光子和电子本质上一样，区别，光子和电子相遇时，光子为客，电子为主，主迎客，永远追不上客
指挥类军校对视力的要求？
军队院校体检条例第三十七条对视力要求：裸眼视力低于4.5，不合格。
任何一眼裸眼视力低于4.9，需进行矫正视力检查，任何一眼矫正视力低于4.9或矫正度数超过600度，不合格。
屈光不正经准分子激光手术后半年以上且无并发症，任何一眼裸眼视力达到4.9，眼底检查正常，除指挥、装甲、测绘、雷达、水面舰艇、潜艇、潜水、空降、特种作战专业外合格。
其中：（一）指挥、装甲、测绘、雷达、水面舰艇、潜艇专业，任何一眼裸眼视力不低于4.9；（二）潜水、空降、特种作战专业，任何一眼裸眼视力不低于5.0。
由此可知，指挥类军校对视力的要求是任何一眼裸眼视力不低于4.9。
