You probably mean "Spectrum".
Radio waves, microwaves and infrared light have a longer wavelength and lower frequency than visible light.
I assume by light rays, you mean visible light rays. In this case, gamma rays have shorter wave lengths.
yes
...colors when the light enters your eyes.
Ultraviolet.
The visible light part of the electromagnetic spectrum is below the ultraviolet but above infrared. Purple light has the highest wave length and red has the lowest.
it's called an ALS alternate light source. it can project light in different wave lengths and spectrums.
Radio waves are electromagnetic energy, similar to light, but of much longer wave lengths.
The frequency of an electromagnetic wave is determined by the speed of light divided by the wavelength of the wave. This relationship is defined by the equation: frequency = speed of light / wavelength.
No. It is totally safe for pregnant women. As such all radiations with wave lengths longer than light wave are safe for pregnant women.
Luminescent glass is a glass containing or coated with a dye that absorbs sunlight. It emits light at longer wave lengths.
The visible light spectrum enters the eye and is focused onto the retina at the back of the eye. The eye's photoreceptor cells, known as rods and cones, are sensitive to different wavelengths of light. Cones are responsible for color vision and are sensitive to different wavelengths corresponding to the colors red, green, and blue.
