Heat is the transfer of thermal energy from a hotter object to a cooler one. This transfer of energy can be felt as an increase in temperature on our skin or in our surroundings. The sensation of heat is due to the activation of heat receptors in our skin, signaling the brain that there is an increase in thermal energy.
The heat felt from the sun is primarily infrared radiation. This type of heat is caused by the sun's energy being absorbed by the Earth's surface and then radiated back as heat.
Infrared radiation is commonly felt as heat. This type of radiation is responsible for the warmth felt from sunlight, fire, or heated objects.
Infrared radiation is the type of radiation that is sometimes felt as heat. It is part of the electromagnetic spectrum and is produced by the vibration and movement of molecules.

No, ultraviolet (UV) radiation cannot be felt as heat because it is not a form of thermal (heat) energy. UV radiation is part of the electromagnetic spectrum and interacts with the skin differently from thermal energy. While UV radiation can cause sunburn and damage to skin cells, it does not produce a sensation of heat like infrared radiation.

Infrared energy is felt as heat, although any type of electronmagnetic energy can be felt as heat if it is sufficiently intense.
Heat that can be measured or felt is called sensible heat. Sensible heat refers to the heat exchange that causes a change in temperature and can be detected by the human senses or measured using a thermometer.
Infrared radiation is commonly felt as heat. This type of radiation is responsible for the warmth felt from sunlight, fire, or heated objects.
Felt is not actually warm, it is just trapping and insulating heat around it.
