The spectrum ranges from violet to red and usually remembered as VIBGYOR
Their wavelength ranges from nearly 3500 to 7000 A (Angstrom unit)
1 A = 10-10 m
To get the frequency simply divide 3 x 108 by the wavelength changed into meter
So for violet the frequeny = 3/3500 x 1018 Hz or 8.57 x 1014 Hz
You could get the frequency of red by the same technique.

What is the frequency range of spectrum?
The frequency range of the spectrum is typically from 20 Hz to 20 kHz, covering the audible range for humans. Beyond this range, there are other frequencies used in areas such as radio waves, microwaves, and infrared radiation.
What are the different ranges of the frequency spectrum?
The frequency spectrum is typically divided into different ranges: Audio frequency range: 20 Hz to 20 kHz, encompassing frequencies audible to humans. Radio frequency range: typically ranges from a few kHz to several GHz, used for communication and broadcasting. Microwave frequency range: typically ranges from several GHz to a few hundred GHz, used in microwave ovens and telecommunications. Infrared and visible light range: above microwaves, including the spectrum of visible light and beyond. Ultraviolet, X-ray, and gamma-ray range: higher frequencies with increasing levels of energy and potential harm.
Is a wave with frequency of 5x10 16 Hz visible?
No, a wave with a frequency of 5x10^16 Hz falls within the range of the electromagnetic spectrum classified as the gamma-ray region. Gamma rays are not visible to the human eye.
What is the range of colours called?
The range of colors is called a spectrum. This refers to the full range of colors that can be produced by the visible light spectrum, typically ranging from red to violet.
What Is the name for the range of electromagnetic waves they are placed in order of increasing frequency?
The answer is electromagnetic spectrum
