Waves

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

Period of a wave is

• The number of waves in one second

• The inverse of wavelength

• The time taken to complete one wave

• The time taken to stop the oscillation

The electromagnetic spectrum is a display of all the electromagnetic waves in the order of increasing
