Visible spectrum contains light of following colours 'Violet - Indigo - Blue -
Green - Yellow - Orange - Red' (VIBGYOR). Its frequency ranges from violet 
to re 
.

(7500 Å)
To find the maximum wavelength in the visible spectrum, you need to use the relationship between wavelength 
and frequency 
of light. This relationship is given by:
where:
is the speed of light in a vacuum, approximately 
meters per second ( 
).
is the wavelength.
is the frequency.
Given:
The frequency range of visible light is from 
(violet) to 
(red).
To find the maximum wavelength, use the minimum frequency because wavelength and frequency are inversely related. The maximum wavelength corresponds to the minimum frequency.
Rearrange the formula to solve for wavelength:
Plug in the values:
(the minimum frequency in the given range)
To convert meters to angstroms ( 1 meter 
angstroms):
So, the maximum wavelength in the visible spectrum is 7500
