Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe wavelength for red color is 7000 Å.
Spectrum of VIBGYOR
The abbreviation of VIBGYOR is red, orange, yellow, green, blue, indigo, and violet.
White light is a combination of various colors where every color can be connected with a particular wavelength of light.
The speed of light is 3 × 108 m/s and is given by:
c = f × λ
where, c = Speed of light
f = Frequency
λ = Wavelength
Since the speed of light is constant. The frequency is inversely proportional to the wavelength.
The spectrum of light is given below:
