Infrared has a longer wavelength, and a lower frequency, than visible light.
Infra-red.
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.
All visible wavelengths are longer than the wavelength of ultraviolet.
Infrared has a smaller wavelength than microwaves.
Infrared Light has a longer wavelength than visible and a shorter wavelength than microwaves.
The wavelengths of visible light are longer than ultraviolet wavelengths.
This statement is incorrect. Infrared rays have a longer wavelength than ultraviolet rays. Infrared rays have wavelengths longer than visible light, while ultraviolet rays have wavelengths shorter than visible light.
Longer than visiblie wavelength is Infrared. Shorther than visible wavelength is ultraviolet. Asking for answers here to the Guardian crossword is cheating. ;o)
Infrared is longer.
The wavelength of visible light is longer than a human skin cell. Visible light has wavelengths ranging from about 400 to 700 nanometers, while a human skin cell is typically around 30 micrometers in size.
The wavelength of infrared radiation is longer than that of visible light. Infrared radiation has wavelengths ranging from about 700 nanometers to 1 millimeter, which are longer than the 400-700 nanometer wavelengths of visible light.
"UV" (ultra-violet) is radiation with shorter wavelength/higher frequency than visible. Infrared is radiation with longer wavelength/lower frequency than visible.
