Answer:
blue wavelength are shorter than red wavelengths.
Step-by-step explanation:
Waves are characterized by regular crests (peaks) and troughs (valleys). Wavelength of a wave is defined by the distance between two successive crests. It is represented by the Greek letter lambda, λ.
Wavelength is related to energy by the equation:
E = hc/λ
Therefore, lower wavelength signifies higher energy and vice versa.
The electromagnetic spectrum extends from the short wavelength, high energy gamma rays to the high wavelength, lower energy radio waves. The short wavelength region of the spectrum is referred as the 'blue' and the longer wavelength is the 'red' end.
