Q. UV radiation and IR radiation have the range of UV Radiation IR Radiation
A) More than 100 nm Less than 400 nm
B) Less than 400 nm More than 700 nm
C) Equal to 400 nm Equal to 700 nm
D) Less than 100 nm More than 100 nm
Explanation
Less than 400 nm, more than 700 nm. Radiation below the visible light (less than 400 nm) are ultraviolet (UV) radiations, while those above (more than 700 nm) the visible light are infra-red or heat waves. Amount of light and its intensity vary with latitude and season. Light intensity, light duration and light quality influence a number of life processes of organisms
