如果物体的光只是一般的漫反射,则不应该有紫外线,因为紫外线的定义是由太阳光而来的,它是紫外线的主要来源（要不就是人类实验需要造出的了）,如果物体直接反射了太阳光,那当然含有紫外线了,紫外线一般交UV,其英文是Ultraviolet,它的波长比可见光短（频率比可见光高一点,但没有x射线高）,所以我们人的眼睛是看不到它的.
UV light is typically found as part of the radiation received by the Earth from the Sun.Most humans are aware of the effects of UV through the painful condition of sunburn.The UV spectrum has many other effects,including both beneficial and damaging changes to human health.
