What is the range of wavelength size for visible light?
approximately 0.4 to 0.7 µm
The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet. Common wavelengths of what we perceive as particular colours from the visible portion of the spectrum are listed below.
What are the frequencies of visible light?
Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 THz.
How do you find a wavelength?
The wavelength is calculated from the wave speed and frequency by λ = wave speed/frequency, or λ = v / f.
What is the maximum frequency of visible light in Hertz?
The maximum possible frequency will be the speed of light divided by the minimum possible wavelength. So that’s 3 times 10 to the 8 meters per second, divided by 380 nanometers, which is times 10 to the minus 9 meters. That gives 7.89 times 10 to the 14 Hertz.
What is the frequency range of visible light in Hz?
Region | Wavelength | Frequency |
---|---|---|
Visible (blue) | 400 nm | 7.5 × 1014 Hz |
Visible (red) | 700 nm | 4.3 × 1014 Hz |
Infrared | 10000 nm | 3 × 1013 Hz |
Microwave | 1 cm | 30 GHz |
What is the wavelength of light that has a frequency of 3 MHz?
