Answer 1

Answer

AnswerAmplitude , frequency and wavelength are the properties of a wave and are interrelated by following formula ,

v=fλ ,whereas voltage is related with electrical measurements i.e. energy of a cell or battery , so it is odd one .

Answer 2

The odd one out is light waves.

• The odd one out should be light waves because light waves are electromagnetic waves while others are mechanical waves.
• All the other waves need a medium to travel while light waves do not need any medium, they can travel in vacuum even.
• Sound waves, Waves on the surface of water and waves on a stretched string require medium, like waves on surface of water require water and waves on a stretched string require a string.
