What are infrared radiations ? How are they detected ? State one use of these radiations

Infrared lamps are used in restaurants to keep the food warm. The infrared radiation is strongly absorbed by water, raising its temperature and that of the food. If the wavelength of infrared radiationis assumed to be 1500 nm, and the number of quanta of infrared radiation produced per second by an infrared lamp (that consumes enregy at the rate of 100 W and is 12% effcient only) is (x xx10^(19) , then the value of x is : (Given: h= 6.665xx10^(-34)J-s)
