What would a red object look like shone onto a blue light?
Red and blue are at opposite ends of the visible light spectrum, red being of low frequency, and blue being of high frequency. Sunlight contains frequencies across the whole frequency range, which appears white. An object that appears white reflects all frequencies. A red object appears red because it reflects red (low frequency) light, and absorbs all other colours. Blue light contains only high frequencies. If you are in a darkened room, lit only by blue light, white objects will appear blue because they are reflecting the blue light, and no other frequency is available. But a red object absorbs high-frequency (blue) light, and since this is the only light in the room, it does not reflect any light. Objects that do not reflect any light appear black. Some objects appear black even in sunlight, because they absorb all frequencies and do not reflect any. So to answer the question, when you have a red object that is lit only by blue light, it will appear black.
What is the frequency range of microwaves light?
Microwave light has a frequency range of approximately 300 MHz to 300 GHz.
What is the frequency for green light?
The frequency of green light is approximately 540 terahertz.
What is the frequency of ultraviolet light?
Ultraviolet light has a frequency range of approximately 7.5 × 10^14 to 3 × 10^16 Hz.
What is the exact frequency range of black light?
Light is not a mechanical wave. So no need to have a material medium to pass through. Even through vacuum light can travel. Because it is an electromagnetic wave. As electrical and magnetic disturbance pass on in the form of transverse wave the distance between successive crests is defined as the wavlength of the wave. Here crest means the field intensity becoming maximum.

What do the visible colars of light represent?
The frequency range of visible light.
What is the frequency for green light?
The frequency of green light is approximately 540 terahertz.

Ultraviolet light has a frequency range of approximately 7.5 × 10^14 to 3 × 10^16 Hz.
Does white exist as a color?
Yes. The color white in light represents all visible frequencies.The reason that a "white" object appears "colorless" is that it is reflecting the entire range of colors. A "black" object is reflecting much less light, absorbing light energy across the entire range of colors.

Light is not a mechanical wave. So no need to have a material medium to pass through. Even through vacuum light can travel. Because it is an electromagnetic wave. As electrical and magnetic disturbance pass on in the form of transverse wave the distance between successive crests is defined as the wavlength of the wave.

What is the frequency range of UV of infrared light?
The frequency range of ultraviolet (UV) light is approximately 7.5 x 10^14 Hz to 3 x 10^16 Hz. The frequency range of infrared light is approximately 3 x 10^11 Hz to 4 x 10^14 Hz. UV light has higher frequencies and shorter wavelengths compared to infrared light.
What are good absorbers of light?
Darker colour indicate better absorption of light. Shiny surface is due to it reflect off the light. When the object to totally dark it is because it absorb all the light and transform to heat. You might want to proof it by placing black object and shiny object in the sun, wait few hour and see which object is hotter.
Which light has Frequency within the visible light spectrum?
Wavelengths in the range of 0.4 - 0.7 microns are visible.
What is the light you can detect with your eyes?
Visible light - electromagnetic waves in the frequency range 430 to 770 teraHz.
What is the frequency range of the various breeds of dog bark?
the speed of light
