Ultraviolet rays cannot be seen or felt.
Ever had a sun-burn? I say UV rays can be felt.
All visible wavelengths are longer than the wavelength of ultraviolet.
Visible light and ultraviolet rays are forms of electromagnetic radiation (EM). So are infrared, microwave and others.
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.
Visible light rays are the only type of rays that are visible to the human eye. Other types of electromagnetic waves like infrared, ultraviolet, x-rays, and gamma rays are not visible.
The Sun produces all the electromagnetic radiation in the visible and near visible range. UV rays are near visible ultraviolet rays.
There are an infinite number of wavelengths above visible, below visible, and within visible. Since reality has infinite resolution, we can imagine varying the wavelength with infinite division. To call out bands of wavelength: Ultraviolet, X-rays, & Gamma rays.
microwaves < infrared < visible < ultraviolet < x-rays < gamma rays .
Ultraviolet rays have short wavelengths compared to visible light, ranging from about 10 to 400 nanometers.
No--ultraviolet, x-rays, and gamma rays are progressively shorter.
radiowaves, microwaves, infra-red, visible, ultraviolet, x-rays, gamma rays
Ultraviolet (UV) radiation has more energy than visible light waves.
Between visible light and X-rays there is ultraviolet light.
