(a) Infrared waves
-
Infrared waves are associated with heat radiation.
-
They are used in physiotherapy to treat muscular strain due to their deep-penetrating heating effect.
-
Correct match: (i) To treat muscular strain
(b) Radio waves
-
Radio waves have the longest wavelengths in the EM spectrum.
-
They are primarily used for broadcasting (radio, TV, and communication signals).
-
Correct match: (ii) For broadcasting
(c) X-rays
-
X-rays have high energy and can penetrate soft tissues but are absorbed by dense materials like bones.
-
They are widely used in medical imaging to detect fractures of bones.
-
Correct match: (iii) To detect fracture of bones
(d) Ultraviolet rays
-
Ultraviolet (UV) rays are strongly absorbed by the ozone layer in the atmosphere.
-
They are harmful in excess but are also used for sterilization and in black lights.
-
Correct match: (iv) Absorbed by the ozone layer of the atmosphere
