Yes, wavelength. A different part of the spectrum. That is what "Heat sensing" devices do, they see a part of the spectrum that human eyes don't.

Light is electromagnetic radiation in the visible part of the spectrum. Technically, we could say that "visible light" is the visible electromagnetic spectrum, while "light" is the rest of the spectrum!
Heat, on the other hand, is a measure of energy transferred to an object.
A ray of visible light can go right through a pane of glass, for example; that's light. But if the ray hits a piece of black paper, the energy of the light is absorbed as heat within the object.

Light is part of the electromagnetic spectrum which ranges from radio waves to gamma rays.
The motion of atoms and molecules creates a form of energy called heat or thermal energy which is present in all matter.
Hope this helps

Light is made up of photons or an electromagnetic wave.
Heat is the amount of kinetic energy a particle has.
They're only connected to eachother because infrared light can interact with matter, giving it energy which heats it up.

ummm ... you see light and feel heat
sometimes light is accompanied by heat ... ie sun rays
i guess the energy used to make light always creates heat like stars, even light bulbs always get hot after they have been left on ...
hope this has been helpful - i was really bad in physics, but this kinda makes sense to me :-)

When something is hot, heat is emitted as Infrared (light). When it is very hot, visible light appear. Heat can be transferred to other object via light emission in vacuum.

Frequency of inferred is slower than visible light spectrum so why does not ultra violet light cool?

Wavelength.

Wavelength is the difference.
Now, do the REST of your homework on your own!
