Detailed explanation-1: -Option (b) is the answer : Infra-Red waves, Light Waves, Ultra-Violet Waves.
Detailed explanation-2: -All of the electromagnetic waves, eg light, infrared, ultraviolet are transverse waves, as are water waves.
Detailed explanation-3: -Examples of transverse waves include vibrations on a string and ripples on the surface of water. We can make a horizontal transverse wave by moving the slinky vertically up and down. In a longitudinal wave the particles are displaced parallel to the direction the wave travels.
Detailed explanation-4: -Light waves are just electromagnetic radiation of certain frequencies in the visible range. Hence, light waves are elctromagnetic waves. And as electromagnetic waves are transverse in nature as stated above, light waves are transverse in nature as well.
Detailed explanation-5: -Sound waves are transverse waves, whereas heat waves-infrared radiation-are longitudinal waves.
