If two waves have the same wavelength but different amplitudes, they can still be considered the same type of light. The type or nature of light is determined by its wavelength, frequency, and the electromagnetic spectrum to which it belongs.
Wavelength represents the distance between two successive peaks or troughs of a wave, while amplitude refers to the strength or height of the wave. Two waves with the same wavelength but different amplitudes can differ in their intensity or brightness, but they are still part of the same wavelength or frequency range within the electromagnetic spectrum.
For example, if we consider visible light, which encompasses a range of wavelengths from approximately 400 to 700 nanometers, two waves with the same wavelength within this range, say 500 nanometers, could have different amplitudes. They would still be classified as visible light and would appear as different intensities or brightness levels of the same color.
In summary, the wavelength primarily determines the type of light, while the amplitude affects the intensity or brightness of the light. Two waves with the same wavelength but different amplitudes can still be considered the same type of light, belonging to the same wavelength range or frequency within the electromagnetic spectrum.
