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.
heat
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.

Sound waves are much longer then light waves.
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.

Infrared radiation like heat.

Light rays are visible and have higher frequency compared to that of heat radiation Heat radiation is nothing but infra red which is not visible to human eyes. They have longer wavelength compared to that of visible light
