Answer:
Difference between mechanical waves and electromagnetic waves
Mechanical Waves
Electromagnetic Waves
These waves require material medium for their
propagation
These waves do not require material medium for their
propagation
These are produced due to vibrations of the particles
of the medium
These are produced due to varying electric and
magnetic fields
These waves have low speed, e.g., speed of
sound in air is 332 m/s at 0°C
These waves have very high speed, i'.e.,
in
vacuum
These have usually low frequency and large wavelength
These have usually high frequency and low wavelength
These waves can be transverse or longitudinal
These waves are only transverse waves
