Some snakes (i.e. the pit vipers) can actually see infrared using a pair of tiny pits that act like infrared pinhole cameras.
All snakes feel the warmth of infrared and seek it out to warm their bodies (they are "cold blooded" and unable to warm themselves).

A heat lamp produces what radiation?
Heat travels in the form of infrared radiation. You don't use radiation todetect radiation. You use a detector that responds to the type of radiationyou're trying to detect. In the case of infrared radiation, your skin makes anexcellent detector.
What if your skin temperature is about 300K in what region of the electromagnetic spectrum do you emit thermal radiation most intensely?
At a skin temperature of 300K, your body will emit thermal radiation most intensely in the infrared region of the electromagnetic spectrum. This is because objects at this temperature emit radiation predominantly in the infrared range, which is why we feel warm around them.
When heat is felt from a burning fire?
Heat is transferred to your body through radiation when you feel the warmth from a burning fire. The fire emits infrared radiation that travels in a straight line and warms up objects it comes into contact with, like your skin. This sensation is due to the transfer of thermal energy from the fire to your body.
What is heat transfer by radiation?
Heat transfer by radiation is the process by which heat is transferred through electromagnetic waves, such as infrared radiation, without the need for a medium. This type of heat transfer can occur through a vacuum and does not require direct contact between the objects involved. Examples include the sun heating the earth and a fire warming a room.
How radiation from the sun penetrates the atmosphere by heating the air?
Radiation from the sun penetrates the Earth's atmosphere and heats the air through a process called absorption. Solar radiation is absorbed by gases and particles in the atmosphere, causing them to gain energy and increase in temperature. This heating of the air creates the thermal energy that we feel as warmth from the sun.
What does not need matter to transfer thermal energy?
Infrared radiation does not require matter to transfer thermal energy. It can travel through vacuum, such as outer space, and is responsible for the heat we feel from the sun.
A heat lamp produces what radiation?

Is heat radiation called infrared radiation?
Yes, heat radiation is often referred to as infrared radiation because it falls within the infrared region of the electromagnetic spectrum. It is the type of electromagnetic radiation that we feel as heat when emitted by objects.
Which property spells the differences between infa-red and ultra-violet radiation?
The main difference between infrared and ultraviolet radiation lies in their wavelengths. Infrared radiation has longer wavelengths than visible light, making it thermal radiation that we feel as heat. Ultraviolet radiation has shorter wavelengths than visible light and can cause sunburn and skin damage.
Is the heat you feel from a fireplace radiation?
Yes, the heat you feel from a fireplace is primarily in the form of radiation. As the fire heats up, it emits infrared radiation that warms objects and people in its vicinity. This is why you can feel the warmth even if you are not directly in front of the fire.
When you feel the warmth of the sun on your face what type of thermal energy transfer are you experiencing?
You are experiencing radiant heat transfer, where the energy from the sun is transferred to your face as infrared radiation.
Why Heat you feel when you sit next to a campfire?
The heat you feel when sitting next to a campfire is due to thermal radiation. As the fire burns, it emits infrared radiation that transfers heat energy to your body. This sensation of warmth is a result of the energy transfer from the fire to your skin, causing it to feel hot.
Can you detect infrared radiation with your body if so how?
Yes, humans can detect infrared radiation as heat. Infrared radiation is absorbed by the skin and can make us feel warm, similar to being in sunlight. However, we cannot see or visualize infrared radiation like we can with visible light.
Food being warmed by infrared light is heat transfer by?
Thermal Radiation.Radiation.There are three main types of heat transfer methods in Thermodynamics. Radiation, Convection, and Conduction. Food warmed by infrared light is heat transfer by radiation. What you feel coming from the infrared lamp is radiant heatenergy.
How is infrared radiation used for?
Infrared is heat. When you feel the warmth of a space heater, you feel the effect of infrared radiation. The other uses are motion detection (infrared sensor) and night-vision (live animals have a heat signature, a blurred image, against a colder background at night). ======================
What type of radiation makes you feel warm?
Infrared radiation is responsible for making you feel warm. It is a form of electromagnetic radiation that produces heat when absorbed by the body. This is why objects like the sun or a heater emitting infrared radiation can create a sensation of warmth on your skin.
Is it true that infrared radiation cannot be seen but it can be felt as heat?
Yes, that is correct. Infrared radiation has wavelengths longer than visible light, making it invisible to the human eye. However, our skin can detect infrared radiation as heat, which is why we can feel it when we stand near sources of infrared radiation, such as a fire or a heater.
