There are many :
radio waves etc
We know that mechanical waves require a medium through which to travel. An example of a mechanical wave is a sound (acoustic) wave. The wave transfers its energy into the medium so that it can propagate through it. In contrast, electromagnetic waves don't require a medium through which to travel. They move perfectly well through the vacuum of space.
A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.
Medium is of two type One is material medium and other one is non-material Material medium are air medium, water medium etc Non-material medium is vacuum or free space If material medium is essential for the propagation of the wave then that wave is named as mechanical wave. Example: sound waves If such a material medium is not a must then the wave is said to be Electro magentic wave. Example: Light waves.
unlike the other waves this one must have it
a free travelling wave the wave which transfers energy from one medium to other medium and it is called as disturbing wave

An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.

The options "medium" and "rope" are correct. "Medium" is the most general term for whatever carries a wave; a "rope" is one possible type of medium.
a free travelling wave the wave which transfers energy from one medium to other medium and it is called as disturbing wave
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
It depends whether the new medium is "heavier" or "lighter" than the previous medium. If it is "heavier" then the wave slows down. If it is "lighter" the wave speeds up.
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
speed
