From the name, you can guess that the energy is in the form of electric and magnetic fields. The wave motion comes from the interplay between them - the rate of change of each causes the other, provided they propagate at what we call the speed of light. When the radiation is absorbed anywhere, it causes agitation of the atoms in the absorber, and we sense this as "heat". We run into the photon issue, where particularly at high frequencies the light appears to arrive in packets.

What kind of energy transfers in a loudspeaker?
Electrical energy is transferred into mechanical energy in a loudspeaker. The electrical signal from the audio source causes the speaker cone to move back and forth, creating sound waves that we hear as sound.
What kind of wave transfers energy but no matter?
A light wave transfers energy without requiring a medium for its propagation. Electromagnetic waves, including light, can travel through space because they consist of oscillating electric and magnetic fields that do not need a material medium to transfer energy.
What kind of Heat transfer does not require matter?
Radiation is a form of heat transfer that does not require matter as a medium. Energy is transferred through electromagnetic waves, such as from the sun to the Earth.
What kind of energy is being transferred when the blender is used?
When a blender is used, electrical energy is being transferred to the blender's motor, which is then converted into mechanical energy to blend the ingredients. The mechanical energy is responsible for turning the blades and mixing the food.
What kind of energy are in light waves?
Light waves contain electromagnetic energy. This energy is in the form of photons, which are packets of electromagnetic radiation that carry energy and momentum.
