Solar radiation consists of ultraviolet, visible and infrared radiations.
Hence, the above statement is true.
Name two sources, each of infrared radiations and ultraviolet radiations.
A radiation P is focused by a proper device on the bulb of a thermometer. Mercury in the thermometer shows a rapid increase. The radiation P is :
(a) infrared radiation
(b) visible light
(c) ultraviolet radiation
(d) X -rays.
Give one use each of (a) microwaves , (b) ultraviolet radiations , (c) infrared radiations, and (d) gamma rays.
Mention three properties of infrared radiations similar to the visible light.
Give two properties of infrared radiations which differ front the visible light.
