Typical light bulbs convert electrical energy into light and heat energy. The light (visible, IR and some UV) radiates away. Some we can see. The bulb heats up. This heat energy is radiated away and -- if it's not in a vacuum -- the heat is also carried away by convection.
IR
Just beyond the limits of visible light are ultraviolet (UV) and infrared (IR) light.
Yes, most objects that are opaque to visible light also stop IR. Water also stops IR.
I can't think of anything that could be those two and nothing but those two. Electronic structure spectroscopy is generally in the UV/Visible band, but I suppose it could extend down into the near IR. Vibrational spectroscopy (with rotational fine structure) is in the IR, but doesn't make it up into the visible region.
heat/IR
Immediately adjacent to the band of visible light, on the end with highest frequency / shortest wavelength.
No.

IR
No, infrared radiation (IR) does not have a higher frequency than visible light. Visible light is above IR on the electromagnetic spectrum. It (visible light) has higher frequency and shorter wavelengths than IR radiation does.
The energy band gap between the cathode and anode is too small to generate photons of higher energy than far IR.Silicon is opaque to visible light (and even IR).
Just beyond the limits of visible light are ultraviolet (UV) and infrared (IR) light.
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
IR: longer wavelength, lower frequency, lower energy per photon.Visible: medium wavelength, medium frequency, medium energy per photon.UV: shorter wavelength, higher frequency, higher energy per photon.
Yes, IR and some red-orange visible light.
