Answer / amita sharma
Infra-red and Ultra-voilet rays:-These are type of invisible radiations. Radiation is energy propagating in the form of electromagnetic waves. Such waves do not require any material medium for their propagation. Infra-red are electromagnetic wave smaller in frequencies that the red ray of “visible” radiations. These are ordinary heat rays and are studied by bolo-meters. Ultraviolet radiations have frequencies greater than those of the violet rays of the “Visible” light. These marked by their heating as well as chemical effects and form producing fluorescence and phosphoresce. These are studied photographically.
