Heat has longer wavelength / lower frequency than visible light.
heat
Shorter or longer than what ? The wavelength of visible light is shorter than that of radio and heat, and longer than the wavelength of X-ray and gamma radiation. And the wavelength of green light is shorter than red light but longer than blue light.
No. Heat is infrared radiation ("infra" means "lower"). Lower frequency means longer wavelength. All radiation is captured by antennas that resonate at the frequency of the radiation. The "antennas" for visible light are electrons that use the radiation to jump into excited states and cause optical neurons to fire. The "antennas" of heat (infrared) are bigger -- they are molecules that jiggle faster when the radiation hits them. That jiggling is heat.

X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.
UV (ultraviolet) radiation, with wavelengths shorter than visible light, is not heat. IV (intravenous) medication is usually administered at room temperature. IR (infrared) radiation, with wavelengths longer than visible light, is heat.
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.

Objects appear white when they reflect all wavelengths of visible light. Reflection of various wavelengths of light means that they are scattering the light back into the space surrounding the object, rather than absorbing that energy.Objects appear black when they absorb all wavelengths of visible light, thus absorbing that energy (some of which is converted to heat).
Sound waves are much longer then light waves.

Electromagnetic waves comprise a complete spectrum of wavelengths, it makes no sense to talk about "individual" waves as is asked in the question.It is also incorrect to talk about the "largeness" of a wave, what is important is the wavelength not the amplitude.The spectrum is divided into portions and names given to the wavelengths within a given portion.Thus portions of the spectrum with wavelengths longerthan that portion of the spectrum called "visible light" are:Infra red light (also called heat)MicrowavesRadio wavesIf we go the other way and look at the portion of the spectrum with wavelengths shorter than visible light, we get:UltravioletX-rayGamma ray
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.
