Warm objects emit infrared waves, which are a type of electromagnetic radiation. These waves are not visible to the human eye but can be felt as heat.
Warm is a rather vague term. If it means neither cold enough to freeze your flesh nor hot enough to burn it, the answer is infrared.
Infrared waves can be used to warm a baby chick with a lamp. Infrared waves are a type of electromagnetic radiation that produce heat when absorbed by objects, making them suitable for providing warmth for the chick.
Microwaves are the type of electromagnetic waves that keep food warm by causing the water molecules in the food to vibrate, generating heat. This heat warms up the food quickly and efficiently.
D. You wear them to keep warm.
Infrared waves are found in the electromagnetic spectrum between microwaves and visible light. They are commonly emitted by warm objects, such as the human body, and are used in applications like thermal imaging and remote controls.

Objects that are not extremely cold, or very hot, but warm (by space standards). This is because those objects emit radio waves with fairly high intensity, but not too much higher energy radiation, which would interfere.
Microwave can be use to transmit pictures.
Many light frequencies give off heat. Infrared is one of those frequencies.
D. You wear them to keep warm.
Sound waves, ocean waves, micro waves, light waves and etc.By the way microwave is not the microwave you warm stuff up in.

Infrared electromagnetic waves transmit thermal energy from a fireplace door. These waves are longer in wavelength than visible light but shorter than microwaves, allowing them to carry heat energy and warm objects without necessarily heating the air in between.
Sound travels faster in warm air because the molecules are more spread out, allowing sound waves to move more quickly. In cold air, molecules are closer together, which slows down the transmission of sound waves.
Any wave can convert to heat energy if it is absorbed. The warmth you feel from the Sun, if that's what you mean, is due to visible light and infrared - both of which are electromagnetic waves.
