Which statement about waves is correctly represented in the classification shown in the figure? 
ALongitudinal mechanical waves can travel only in solids
BTransverse mechanical waves can travel only in solids
CElectromagnetic waves require a material medium
DMatter waves are a type of mechanical wave
Answer & Solution
Correct answer: B. Transverse mechanical waves can travel only in solids
The figure classifies waves into mechanical and non-mechanical, and under mechanical waves it shows transverse waves as occurring only in solids, while longitudinal waves can occur in solids and fluids. Electromagnetic waves are non-mechanical, so they do not require a material medium. Therefore B is the correct statement.
