Heat has longer wavelength / lower frequency than visible light.
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.
Microwave ovens use longer light rays than the visible light rays we can see. Microwave radiation has a longer wavelength, which allows it to penetrate and heat food without being visible to the human eye.
The wave that is shorter than a microwave and longer than visible light is called an infrared wave. Infrared waves have wavelengths longer than visible light waves but shorter than microwaves, making them useful for various applications such as thermal imaging and communication technology.
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.
Yes, heat, in the context of thermal radiation, typically refers to infrared radiation, which has longer wavelengths than visible light. While visible light ranges from about 400 to 700 nanometers, infrared radiation has wavelengths from about 700 nanometers to 1 millimeter. Therefore, heat (infrared) does not have shorter wavelengths than visible light; instead, it has longer wavelengths.

No, green wavelengths are shorter than orange wavelengths. In the electromagnetic spectrum, longer wavelengths correspond to colors such as red and orange, while shorter wavelengths correspond to colors like blue and green.
Those gasses that allow the passage of shorter wavelength energy such as light but reflect or absorb longer wavelength energy such as heat. The main such gasses in our atmosphere are water vapour and carbon dioxide.
It depends on the wavelength of light and the amount of heat. If you are comparing light from the visible part of the spectrum with infra red (i.e. heat), then visible light has more energy due to its slightly shorter wavelength. Energy is related to wavelength by the equation E=hc/λ where h is Planck's constant, c is the speed of light in a vacuum and λ is wavelength.

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.
Red light has a longer wavelength and lower frequency than violet light. When light is absorbed by an object, the energy is converted into heat. The shorter wavelength and higher frequency of violet light means it carries more energy, but red light is absorbed more efficiently by most objects, making it appear hotter.
The Earth emits longer wavelength infrared radiation because it absorbs sunlight and re-radiates it as heat. The Sun, on the other hand, emits shorter wavelength radiation in the form of visible light because it is much hotter than the Earth.
