heat
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.
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
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.
Not even close. Microwaves are much longer, with a lower frequency, than light is.The shortest 'microwave' is in the neighborhood of 1 millimeter long (300 GHz).That's about 1,540 times as long as the longest visible wave (red, 650 nm)).
Infrared Light has a longer wavelength than visible and a shorter wavelength than microwaves.

microwave
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.

Visible light. The higher the frequency, the shorter the wavelength.
"shorter"
Microwave, infrared, and visible light are all forms of electromagnetic radiation. Microwave has longer wavelengths and lower frequencies, often used for communication and cooking. Infrared has shorter wavelengths than microwaves and is commonly used in night vision technology. Visible light is the range of wavelengths that the human eye can detect, making it essential for vision and various technologies.
Infrared Light has a longer wavelength than visible and a shorter wavelength than microwaves.
shorter
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
