Question

What type of wave does not need a medium to transfer its energy ?

Answer 1

A wave is a disruption in a medium that transports energy without causing net particle movement. Different forms of waves include sea waves or tides, a sound we hear, a photon of light travelling, and even the movement of small plants blown by the wind.

Complete answer:
The fusion of electric and magnetic fields produces electromagnetic waves. Electromagnetic waves are responsible for the light we see and the colours we see around us.Electromagnetic waves, unlike mechanical waves, do not need the presence of a medium in order to propagate. This means that electromagnetic waves will pass through the vacuum of space as well as through air and solid materials. In a vacuum, all electromagnetic waves propagate at the same speed.

A wave is an oscillating flow or movement of energy through a medium such as space or mass. Waves come in a variety of shapes and sizes, each with its own set of characteristics. There are three categories of waves based on the particle motion orientation and energy direction. They are: Mechanical waves, Electromagnetic waves and Matter waves.

Hence, the type of wave that does not need a medium to transfer its energy is electromagnetic waves.

Note: The electromagnetic wave is the only wave that is not mechanical. Waves that aren't mechanical can pass through vacuum. Examples of electromagnetic waves are Radio signals, light rays, x-rays, and cosmic rays.
