B. Red light has a longer wavelength C. Red light has a longer Wavelength D. Red light has a higher frequency If you could explain why that would be amazing thanks
There is no A? B and C are the same?
Red light has a longer wavelength
B Light is an electromagnetic wave, which means it's a wave-like disturbance in the electric and magnetic fields that permeate the Universe. As a wave, it has the wave properties of wavelength and frequency. We perceive different wavelengths of light as different colors, with red light being at the long wavelength/low frequency end of the visible spectrum, and violet light being at the short wavelength/high frequency end. Wavelength and frequency have a reciprocal relationship, meaning that if one is big, the other is small (and vice versa). You can see this from the equation for the velocity of a wave: c = f·λ Where c is the speed of light (a constant), f is the frequency of the wave, and λ is the wavelength. Rewriting this, you get: f = c / λ and λ = c / f
