What is the frequency range of visible light?
It ranges from 4.28 x 1014 Hz for red light to 7.89 x 1014 Hz for violet light.
That depends on whether it's still in the visible light range that human eyes can detect. If it's beyond red it will be infrared, a light wave with wavelength/frequency that we cannot detect. The frequency range of red light is between 484 THz to 384 THz. The wavelength of visible red light is between 620 nm to 750 nm.
Just as in the case of sound, the limits of perception depend on the individual eye and on the intensity/brightness of the light. A rough idea of the frequency range of visible light is: 375 to 770 THz. (375,000 to 770,000 GHz) (375,000,000 to 770,000,000 MHz) (375,000,000,000 to 770,000,000,000 KHz) (375,000,000,000,000 to 770,000,000,000,000 Hz)
With sound, lower frequencies are heard as lower pitch, and higher frequencies are heard as higher pitch. With visible light, the frequency of the vibration is interpreted as color. For visible light, lower frequencies are towards the red, and higher frequencies toward the blue. Outside the range of visible light, differences in light frequency can be detected by instruments, but they are not usually referred to as colors.
Visible light has a frequency range between 7 x 10 to the 4th power and 4 x 10 to the 4th power. Which frequency of light would have the most energy?
Normal sunlight is composed of electromagnetic waves of frequencies encompassing the entire visible light range, as well as some wavelengths outside the visible range (such as infra-red and ultraviolet). All these visible frequencies combined makes white light. Any object that appears blue in sunlight reflects the blue part of the visible light (at the high-frequency end of the visible spectrum), and absorbs the other colours.
Yes, it is. Electromagnetic (EM) waves have frequency and amplitude (as well as polarity and a couple of other things), and because it has frequency, it can be distributed across a range of frequencies, or a spectrum - an electromagnetic spectrum. Light is a range of frequencies in what we call the optical or visible range. It is bounded on the lower end (lower frequency, lower energy, longer wavelength) by infrared (IR) light, and on…
