Echo

A wave is defined as the

• Transfer of matter without the transfer of energy

• Transfer of energy without the transfer of matter

• Transfer of energy and matter

• Transfer of light and sound with the transfer of matter

Wavelength of a wave is

• The maximum displacement of a particle from rest position

• The distance between a crest and a trough in the same wave

• The distance between two adjacent troughs

• The distance between any two crests in the wave

Sound is a

• Longitudinal wave

• Transverse wave
