Heat is a form of energy that does not emit visible light. It can only be perceived indirectly through its effects, like feeling hot or detecting an increase in temperature. Our eyes can only detect certain wavelengths of electromagnetic radiation, so we are unable to "see" heat in the same way we see visible light.
Invisible heat radiated from objects is in the form of infrared radiation. This type of radiation is not visible to the human eye but can be felt as heat when it strikes the skin.
Invisible heat is typically carried by electromagnetic waves known as infrared radiation. These waves are not visible to the human eye but can be felt as heat when they come into contact with objects.
The invisible heat from the sun is called infrared radiation. This type of radiation is not visible to the human eye but can be felt as warmth on the skin.
An infrared lamp will emit invisible heat radiation. These lamps are designed to produce infrared light, which is not visible to the human eye but produces heat when absorbed by objects.

An infrared lamp will show invisible heat radiation. Infrared lamps emit infrared light, which is not visible to the human eye but can be felt as heat due to its longer wavelength compared to visible light.
The hypothesis of an invisible ink could be that the ink will become visible when exposed to a certain type of light or heat, based on the properties of the ink's chemical composition.
Yes, baking soda can be mixed with water to create invisible ink. When the solution dries on paper, the writing becomes invisible and can later be revealed by applying heat or a second solution (such as vinegar).
Fire can be caused by any concentration of heat, in flammable materials. The cause can include visible or invisible radiation.
To reveal invisible writing made with lemon juice, you can heat the paper gently with a hairdryer or place it near a light bulb. The heat will cause the lemon juice to oxidize and turn brown, making the writing visible.
