Question

MCQ: Waves which require medium for propagation are
electromagnetic
mechanical
transverse
longitudinal​

Answer 1

Answer:

Waves which require medium for propagation are electromagnetic.

Answer 2

ELECTROMAGNETIC WAVES

Waves which require medium for propagation are ELECTROMAGNETIC

CHARACTERISTICS OF ELECTROMAGNETIC WAVES:

*Electromagnetic radiation has a wide variety of wavelengths and frequencies, each of which corresponds to a different energy intensity and amount.

* An electromagnetic wave travels in a path perpendicular to the vibrations of both the electric and magnetic oscillating field vectors, transferring energy from the source to an unknown final destination. 

* Electromagnetic waves travel at the speed of light.
