Answer :
Blue light has shorter wavelengths, 450–495 nanometers, on average. Blue light has a higher frequency and much more energy than red light.
Why is wavelength significant?
The wavelength of an electromagnetic wave provides details about its length. The distance here between "crests" (tops) of related waves is known as the wavelength. The same wavelength can also be determined by making observations from the "groove" (bottom) from one waveform to the "trough" of the next.
What types of wavelength are there?
Examples of electromagnetic fields with particular wavelengths & greater frequency include gamma rays, Cross, and ultraviolet light. Longer wavelengths & lower harmonics of electromagnetic fields include thermal light, microwaves, radio signals, and televisions waves.
